Question 1

Does this work on old, dried urine stains or only fresh accidents?**

Accepted Answer

Most users find it effective on fresh to moderately dried stains (up to a few days old). For older, set-in odors, you may need to saturate the area heavily or reapply 2–3 times. On TikTok, some pet owners suggest letting it sit for an hour and blotting repeatedly—this helps more on old spots. If the stain has been there for weeks, consider first using a carpet cleaner extractor before applying.

Question 2

Is the smell of the formula itself unpleasant?**

Accepted Answer

Yes, several buyers note a strong “bio” or enzyme smell when first applied—some describe it as yeasty or slightly sour. This is normal and fades completely as the liquid dries (usually within 1–2 hours). If your cat is sensitive to odors, open a window during application. Many Reddit users mention that the final result is odor-free, but the initial wet phase can be off-putting.

Question 3

Can I use this on my couch, mattress, or car upholstery?**

Accepted Answer

Yes, but results vary by fabric type. It works well on waterproof or tightly woven materials (leather, vinyl, polyester). On thick upholstery or memory foam, the liquid may not reach deep enough to fully neutralize the odor—some couch owners reported smell returning days later. Always test on an inconspicuous spot first, and for thick cushions, consider using a handheld carpet cleaner to push the formula deeper.

Question 4

Will this stop my cat from re-peeing in the same spot?**

Accepted Answer

Many pet owners report success with breaking the re-soiling cycle—the enzymes remove the ammonia scent that attracts cats back. However, if your cat is marking due to territorial stress (especially male cats), this may not eliminate the behavior on its own. For best results, combine product use with a thorough vet check and stress reduction for your cat.

Question 5

How does this compare to other stain removers like Rocco & Roxie or white vinegar?**

Accepted Answer

This product is a solid budget-friendly choice for everyday accidents and hard floors. Many users who tried Rocco & Roxie say it’s stronger on carpet odors but costs nearly double per ounce. Vinegar and baking soda can work for light freshening, but they don’t truly break down the bacteria in urine. If you have thick carpets or male cat spray, you may prefer a professional-grade enzyme cleaner—otherwise, this is a reliable starting point.
