Question 1

Will this remove tough smells like pet urine or cigarette smoke from carpets and upholstery?**

Accepted Answer

Yes, many users—especially pet owners—report it’s effective on deep-set odors like urine and smoke. The formula works by neutralizing molecules rather than masking them. For best results on carpets, spray until slightly damp, let dry completely, and vacuum. Some TikTok reviewers noted it works better on hard surfaces, so test on a small fabric area first if you’re concerned about residue.

Question 2

Is it safe to use around children, pets, or people with sensitivities?**

Accepted Answer

The product is marketed as non-toxic and safe for use around people and pets when used as directed. However, a number of Reddit users mentioned they experienced mild respiratory irritation or headaches in small, unventilated rooms. To be cautious, we recommend spraying in well-ventilated areas and keeping pets and children away until the spray has fully dried. If you have known chemical sensitivities, consider a smaller bottle to test.

Question 3

Does this leave a white residue on dark surfaces or clothing?**

Accepted Answer

This has been the most common complaint across reviews. On hard, non-porous surfaces like plastic or glass, it dries clear. On dark fabrics, carpets, or unsealed wood, some users report a white, powdery film once dry. If you plan to use it on clothing or dark upholstery, we suggest doing a spot test in an inconspicuous area first. To avoid buildup, don’t oversaturate.

Question 4

How long does the odor elimination actually last?**

Accepted Answer

It varies depending on the surface and the intensity of the smell. Many users find it effective for 1 to 3 days on fabrics, while stronger odors like smoke may need reapplication every 4–6 hours in the beginning. The product is great for spot treatments, but it’s not a “set and forget” solution—you may need to respray after vacuuming or cleaning the area. Some fans keep a bottle in their car for quick touch-ups.

Question 5

This says “unscented” but I smell something. Is it supposed to have a scent?**

Accepted Answer

Zero Odor is formulated to be an unscented odor eliminator, meaning it won’t add a perfume fragrance. However, several buyers have described a faint “cleaner” or slightly chemical smell while it’s wet. This usually fades completely once dry. If you’re looking for a product that leaves a fresh linen or floral scent, this isn’t the right choice—you might prefer a traditional air freshener. For true neutralization without added fragrance, this spray delivers.
