What Is NonScents Stain and Odor Eliminator?
NonScents Stain and Odor Eliminator is a professional-strength, enzyme-based cleaner specifically formulated to tackle persistent pet urine odors. Unlike traditional cleaners that mask smells with synthetic fragrances, NonScents uses biological enzymes to break down urine crystals at the molecular level — permanently eliminating the odor source.
The fragrance-free formula is a significant advantage for pet owners whose dogs or cats have asthma, allergies, or general scent sensitivities. Many “pet-safe” cleaners still contain masking fragrances that can irritate sensitive respiratory systems. NonScents removes the smell without adding any scent.

How NonScents Works: Enzyme-Based Urine Elimination
Unlike air fresheners or fabric sprays that only mask odors, NonScents uses enzyme technology to eliminate the source of pet urine smells permanently.
The Science of Urine Odor
Pet urine contains uric acid crystals that embed deep into carpet fibers, padding, and even subfloors. These crystals don’t break down with regular cleaners. They can remain active for years, continuing to release odor and — most importantly — acting as a beacon for your pet to re-soil the same spot.
How Enzymes Work
NonScents uses specific biological enzymes that:
- Target uric acid crystals — Enzymes break down the molecular structure of urine crystals
- Digest organic matter — Enzymes consume the proteins and bacteria that cause odors
- Permanently eliminate the source — Once broken down, the odor cannot return
- Remove pet scent markers — Eliminates the pheromones that tell pets “this is a bathroom spot”
Why Fragrance-Free Matters
| Feature | NonScents (Fragrance-Free) | Typical Enzyme Cleaners (With Fragrance) |
|---|---|---|
| Odor elimination | Enzymes break down urine crystals | Enzymes break down urine crystals |
| Added scent | None | Yes — synthetic or natural fragrances |
| Pet respiratory safety | Excellent — no irritants | Moderate — fragrances can irritate |
| Pet behavioral impact | No scent to attract or repel | Scent may deter some pets (or attract others) |
| Human sensitivity | Safe for allergies, asthma | May trigger reactions |
“Fragrance-free doesn’t mean less effective. In fact, for pets with asthma or allergies, fragrance-free is superior. The enzymes do the work — the fragrance is just marketing. NonScents skips the marketing and delivers the science.”

Ingredient Safety Analysis: Why Fragrance-Free Matters for Pet Health
This is a critical differentiator for NonScents. Dr. Jackson has reviewed the fragrance-free formula specifically for pets with respiratory conditions.
Dr. Jackson’s Clinical Assessment on Fragrance-Free Cleaners
“As a veterinarian, I see many pets with asthma, chronic bronchitis, and environmental allergies. One of the most common triggers I identify is household fragrances — from candles, plug-in air fresheners, scented sprays, and even ‘pet-safe’ cleaners that still contain masking scents.
NonScents stands out because it’s genuinely fragrance-free. No ‘natural’ essential oils. No ‘light’ scents. No fragrance at all. This is a significant advantage for pets with respiratory sensitivity.
The enzyme technology works regardless of whether fragrance is added. The fragrance is purely for human preference — it doesn’t help the cleaning process. So when a brand skips the fragrance, they’re not cutting corners. They’re prioritizing the health of sensitive household members, both human and animal.
For cat owners dealing with inappropriate urination (marking behavior), fragrance-free is also advantageous. Some cats are deterred by strong scents and may avoid the litter box if you clean it with fragranced products. NonScents eliminates the urine odor without adding any new scent that might confuse or deter your cat.
I recommend NonScents to clients whose pets have confirmed fragrance sensitivities or respiratory conditions. It’s also my top recommendation for kitten and puppy households — young animals have developing respiratory systems that are more vulnerable to irritants.”
— Dr. Allona Jackson, DVM

| Fragrance | None — intentionally omitted | ✅ EXCELLENT | No respiratory irritants; ideal for sensitive pets |
| Preservatives | Maintain product stability | ✅ SAFE | Cosmetic-grade preservatives in safe concentrations |
| Colorants | None — clear formula | ✅ EXCELLENT | No artificial dyes to stain carpets or irritate paws |
Red Flag Ingredients — NOT Found in NonScents
| Chemical | Why It’s Dangerous | Status in NonScents |
|---|---|---|
| Phthalates | Endocrine disruptor | ❌ NOT present |
| Ammonia | Respiratory irritant | ❌ NOT present |
| Bleach | Corrosive, toxic | ❌ NOT present |
| Synthetic fragrances | Respiratory irritant, allergen | ❌ NOT present |
| Essential oils | Can be toxic to cats | ❌ NOT present |
| Formaldehyde | Known carcinogen | ❌ NOT present |
The 1-Gallon Advantage: Value for Multi-Pet Households
NonScents is available in several sizes, but the 1-gallon jug offers the best value for pet owners who need a reliable, heavy-duty enzyme cleaner.
Size Comparison
| Size | Approximate Price | Price per Ounce | Best For |
|---|---|---|---|
| 1 Gallon (128 oz) | $39.95 | $0.31/oz | Multi-pet households, heavy use, professional applicators |
| 32 oz | ~$15-20 | ~$0.47-0.63/oz | Single-pet households, occasional use |
| 12 oz (2-pack) | ~$12-15 | ~$0.50-0.63/oz | Travel, small spaces, first-time trial |
Cost Per Use Analysis
| Surface Type | Approximate Coverage | Cost per Use (1 Gallon) |
|---|---|---|
| Small urine spot (6″ circle) | 2-3 oz per spot | 0.62−0.93 |
| Medium stain (12″ circle) | 4-6 oz per spot | 1.24−1.86 |
| Whole-room carpet refresh | 16-32 oz | 4.96−9.92 |
| Litter box deep clean | 8-12 oz | 2.48−3.72 |
For multi-pet households or owners dealing with repeated marking behavior, the 1-gallon size saves significant money compared to buying 12-32 oz bottles repeatedly.
*”If you have one small dog who never has accidents, a small bottle of enzyme cleaner might last a year. But if you have three cats, a senior dog with incontinence, or a puppy in training, you’ll go through small bottles fast. The 1-gallon jug pays for itself after the second or third accident.”*

Where to Use NonScents
NonScents is designed as an all-in-one solution for pet stains and odors. Here’s where it works best.
✅ Ideal Use Cases
| Location | Why It Works | Application Tip |
|---|---|---|
| Carpet urine stains | Enzymes penetrate fibers to break uric acid crystals | Saturate stain, let dwell 10-15 min, blot |
| Hardwood floors | Safe for sealed floors; no fragrances to damage finish | Apply to cloth, not directly to floor |
| Tile and grout | Enzymes penetrate porous grout where urine hides | Apply generously to grout lines |
| Furniture upholstery | Safe for most fabrics; test in hidden area first | Light mist, blot, air dry |
| Litter boxes | Fragrance-free won’t deter cats from using box | Clean box, spray, rinse thoroughly |
| Pet kennels and carriers | Removes odors from plastic and fabric | Spray, let sit, rinse well |
| Trash cans | Eliminates organic odors | Spray interior, let sit, rinse |
| Cat marking spots | Fragrance-free won’t add deterrent or attractant | Treat as urine stain |
⚠️ Where to Test First
| Surface | Precaution |
|---|---|
| Unsealed hardwood | Test in hidden area; excessive moisture may damage |
| Delicate silks or velvets | Test hidden area; blot don’t saturate |
| Natural stone (marble, travertine) | Test hidden area; enzymes are generally safe but test first |
| Unsealed grout | May darken temporarily while wet; dries to original color |
❌ Where NOT to Use NonScents
| Location | Why Not | Better Alternative |
|---|---|---|
| As daily air freshener | Not designed for airborne odors | Levoit air purifier |
| For general fabric refresh | Overkill for light pet dander | Febreze Fabric Pet |

How to Use NonScents Correctly: Step-by-Step
Proper technique is essential for enzyme cleaners. Follow these steps for maximum effectiveness.
Step 1: Purchase a Pump Sprayer
The 1-gallon jug does NOT include a sprayer. You’ll need a separate pump spray bottle or trigger sprayer. Any standard 16-32 oz spray bottle works.
Cost factor: Add $5-10 for a sprayer if you don’t already have one.
Step 2: Pour into Spray Bottle
Fill your spray bottle with NonScents concentrate (it comes ready-to-use — no dilution needed unless specified).
Step 3: Remove Excess Moisture
For fresh stains: Blot up as much urine as possible with paper towels or clean cloths. Do not rub — rubbing pushes stain deeper into fibers.
For set-in stains: Vacuum any dried debris first.
Step 4: Saturate the Stain
Spray generously until the stain is thoroughly wet. Enzyme cleaners need to reach the full depth of the stain — including carpet padding if urine penetrated that far.
Step 5: Let It Dwell (Critical Step)
| Stain Type | Minimum Dwell Time |
|---|---|
| Fresh urine (still wet) | 10-15 minutes |
| Set-in urine (dried) | 15-20 minutes |
| Old, recurring spot | 30-60 minutes (cover with plastic wrap to keep wet) |
| Deep pad saturation | Overnight (cover with plastic wrap) |
Why dwell time matters: Enzymes need time to break down uric acid crystals. Rushing this step is the #1 reason enzyme cleaners “fail.”
Step 6: Blot Excess Moisture
After dwell time, blot with clean, dry towels to remove excess moisture.
Step 7: Air Dry Completely
Allow the area to air dry. Enzymes continue working as they dry. Keep pets away until the area is completely dry.
Step 8: Repeat if Necessary
For deep, old, or recurring stains, a second application may be needed. Old urine that has soaked into carpet padding may require treating both the carpet and the pad (pull back carpet if possible).
Pro Tips from Ahashanul
“For urine that has soaked into carpet padding, the only permanent solution is treating both the carpet AND the pad. If you can pull back the carpet corner, spray NonScents directly on the pad, let it dwell, then blot. For subfloor contamination, you may need professional help.”
“Use a black light to find all urine spots. What you can’t see, you can’t treat. Many owners treat one spot while missing three others — then wonder why the smell returns.”

Frequently Asked Questions (FAQ)
Here are the most common questions pet owners ask about NonScents Stain and Odor Eliminator.
1. Is NonScents truly fragrance-free?
Answer: Yes. NonScents contains no added fragrances, essential oils, or masking scents. The formula has no scent at all. This is verified by the product specifications (“Unscented”) and customer reviews.
“For pets with asthma or fragrance allergies, ‘unscented’ is often better than ‘lightly scented.’ NonScents delivers genuine fragrance-free cleaning.”
— Dr. Allona Jackson, DVM
2. Does NonScents work on old, set-in urine stains?
Answer: Yes, but may require multiple applications. NonScents is formulated as a professional-strength enzyme cleaner specifically for persistent pet urine odors.
For best results on set-in stains:
- Saturate the stain thoroughly (it must reach carpet padding)
- Cover with plastic wrap to keep wet
- Allow extended dwell time (30-60 minutes or overnight)
- Blot, air dry, and repeat if needed
- For deep pad contamination, consider pulling back carpet to treat pad directly
3. Is NonScents safe for cats?
Answer: Yes, with one major advantage. NonScents is non-toxic and fragrance-free, making it safer for cats than many scented alternatives.
Why fragrance-free matters for cats:
- Cats have extremely sensitive respiratory systems
- Essential oils in scented products can be toxic to cats
- Strong scents may deter cats from using treated litter boxes
- Fragrance-free eliminates these risks entirely
“I specifically recommend NonScents to cat owners dealing with inappropriate urination. The fragrance-free formula won’t add scents that might confuse or deter your cat from returning to the litter box.”
— Dr. Allona Jackson, DVM
4. How does NonScents compare to Rocco & Roxie?
Answer: Both are excellent enzyme cleaners with similar effectiveness. The main differences:
| Feature | NonScents | Rocco & Roxie |
|---|---|---|
| Fragrance | Unscented | Light, pleasant scent |
| Size options | 1 gallon (best value) | 32 oz, 1 gallon |
| Price per oz | $0.31/oz | ~$0.78/oz (32 oz) |
| Best for | Fragrance-sensitive households | General use, preferred scent |
| Reviews | 1,128 reviews (4.3★) | 65,000+ reviews (4.8★) |
Choose NonScents if: Your pet has asthma/allergies, you prefer fragrance-free, or you want the gallon size for value.
Choose Rocco & Roxie if: You prefer a light scent, want a more reviewed product, or prefer smaller bottles.
5. Can I use NonScents in my carpet cleaning machine?
Answer: Check your machine manual first. Most carpet cleaners specify which solutions are safe to use. NonScents is a liquid enzyme cleaner, not specifically formulated for carpet cleaning machines.
General guidance:
- Upright carpet cleaners (BISSELL, Hoover, etc.): Use manufacturer-recommended solutions
- Portable spot cleaners: NonScents can be used as a pre-treatment, not in the tank
- For machine cleaning, consider a formula designed for your specific machine
6. Does NonScents need to be rinsed after use?
Answer: Generally, no. For most surfaces (carpet, upholstery, sealed floors), NonScents can be left to dry without rinsing. The enzymes break down and become inert as they dry.
When to rinse:
- On food-contact surfaces (wipe clean)
- On litter boxes (rinse thoroughly before adding litter)
- On pet bowls or kennel food areas (rinse)
- When residue remains after drying (unlikely with proper application)
7. How long does a 1-gallon jug last?
Answer: Depends on usage frequency.
| Household Type | Accidents per Week | Estimated Lifespan |
|---|---|---|
| Single cat, no accidents | 0 | 2+ years (may expire before use — check expiration) |
| Single dog, occasional accidents | 1-2 | 6-12 months |
| Multi-pet, frequent accidents | 3-5 | 3-6 months |
| Puppy in training | 5-10 | 1-3 months |
| Cat with marking behavior | 5-10 (small spots) | 2-4 months |
The 1-gallon size is best for: Multi-pet households, puppies in training, senior pets with incontinence, cat owners dealing with marking.
8. Can I use NonScents on hardwood floors?
Answer: Yes, on sealed hardwood. For sealed hardwood, laminate, or engineered wood floors:
Application method:
- Spray NonScents onto a cloth, not directly on the floor
- Wipe the stained area
- Allow to dry (enzymes continue working)
- Wipe away any residue if needed
Do not apply to: Unsealed wood, water-damaged wood, or wood with cracked finish (moisture can seep in).
9. Is NonScents safe for use around children?
Answer: Yes. NonScents is formulated to be non-toxic and safe for homes with children and pets. However, as with any cleaning product:
- Keep out of reach when not in use
- Use in well-ventilated areas
- Do not allow children to handle the concentrate
- Rinse surfaces that come into contact with food
10. Why does NonScents have fewer reviews than Rocco & Roxie?
Answer: Brand awareness and marketing. Rocco & Roxie has been heavily marketed on Amazon and social media, accumulating over 65,000 reviews. NonScents has a smaller but loyal customer base (1,128 reviews at 4.3★).
Does fewer reviews mean less effective? No. NonScents is manufactured by OxiScience, a company specializing in enzyme-based cleaning. The 4.3★ rating with 1,000+ reviews indicates satisfied customers.
Our assessment: NonScents is equally effective as Rocco & Roxie for urine stain removal. The choice comes down to:
- Fragrance preference (NonScents wins for unscented)
- Size preference (NonScents wins for 1-gallon value)
- Brand trust (Rocco & Roxie wins for social proof)
Veterinary Perspective: Fragrance-Free Benefits for Pets
Dr. Allona Jackson, DVM, on NonScents for Pets with Respiratory Conditions
“In my veterinary practice, I see an increasing number of pets with asthma, chronic bronchitis, and environmental allergies. One of the most common triggers I identify — and one of the easiest to eliminate — is household fragrances.
Many pet owners don’t realize that ‘pet-safe’ on a label doesn’t guarantee ‘fragrance-free.’ Even products marketed for pets often contain synthetic or ‘natural’ essential oil fragrances that can irritate sensitive respiratory systems.
NonScents is different. It’s genuinely fragrance-free. No added scent. No essential oils. No masking fragrances. Just the enzymes that do the work.
For cats with asthma, this is a game-changer. Their airways are tiny and reactive. A scented litter box cleaner or carpet spray can trigger wheezing within minutes. NonScents eliminates the urine odor without adding any respiratory irritant.
For dogs with chronic bronchitis, the same principle applies. Every irritant you remove from their environment reduces the workload on their already-stressed lungs.
*I also appreciate the 1-gallon size for multi-pet households. When you’re dealing with repeated accidents — a senior dog with incontinence, a cat with marking behavior, a puppy in training — you go through enzyme cleaner fast. The gallon jug makes economic sense and ensures you always have product on hand.*
My bottom line: NonScents is the enzyme cleaner I recommend for fragrance-sensitive households. For homes without respiratory concerns, Rocco & Roxie is also excellent. But if your pet has asthma, allergies, or you simply prefer unscented products, NonScents is the superior choice.”
— Dr. Allona Jackson, DVM

Final Verdict
Best For
- ✅ Pet owners with fragrance-sensitive pets (asthma, allergies, chronic bronchitis)
- ✅ Multi-pet households with frequent accidents
- ✅ Cat owners dealing with inappropriate urination or marking behavior
- ✅ Owners who prefer unscented cleaning products
- ✅ Puppy training and housebreaking
- ✅ Senior pets with incontinence
- ✅ Value-seekers who want best per-ounce price
- ✅ Homes with both pets and infants/children
Not For
- ❌ Owners who prefer scented cleaning products (choose Rocco & Roxie instead)
- ❌ First-time enzyme cleaner users (smaller bottle may be better trial size)
- ❌ Those without a pump sprayer (adds $5-10 to initial cost)
- ❌ Daily fabric refresh (use Febreze Fabric Pet instead)
- ❌ Airborne odor control (use Levoit air purifier instead)
The Bottom Line
*”NonScents Stain and Odor Eliminator is the best choice for pet owners who need a fragrance-free, professional-strength enzyme cleaner. The 1-gallon size offers exceptional value for multi-pet households, and the unscented formula is a major advantage for pets with asthma, allergies, or fragrance sensitivities.*
Is it the right choice for everyone? No. If you prefer a light scent or want a smaller bottle to try first, Rocco & Roxie might be a better starting point. But if you know you need a heavy-duty, fragrance-free solution — especially for cats with marking behavior or dogs with respiratory issues — NonScents delivers.
*The one catch: you’ll need to buy a sprayer separately. That adds $5-10 to your initial cost. But once you have the sprayer, the gallon jug keeps you stocked for months.*
For the complete fragrance-free system, pair NonScents liquid enzyme with the Levoit air purifier for dander control and NonScents charcoal bags for passive odor absorption. That’s three products, zero fragrances, complete coverage.”
