Why pet odor comes back after cleaning
Urine soaks through carpet into the padding and sometimes the subfloor. Cleaning only the visible spot leaves the source behind, so the smell returns, especially on humid days. Cat urine is particularly stubborn: its compounds can't be removed with ordinary water and soap.
How we remove it
- A urine detection light shows affected areas the eye can't see.
- Bio Modifier Enzyme Eradicator solution breaks down the urine rather than masking it.
- We treat every affected layer: carpet, pad, subfloor and baseboards.
- The carpet is then deep cleaned so the whole room looks and smells fresh.
What pet owners should know
Blot accidents as soon as you find them and keep the labels of any products you've tried; some store-bought cleaners set stains. Read our guide to carpet deep cleaning for pet stains and odors.
Questions about pet odor removal
Can you remove cat urine smell from carpet?
Yes. Cat urine can't be removed with water and soap alone, so we use a Bio Modifier Enzyme Eradicator solution and treat the carpet, pad, subfloor and baseboards where the odor starts.
Why does pet odor return after the carpet is cleaned?
Because the urine reached the padding or subfloor. Surface cleaning leaves that source behind. Gemstone finds it with a detection light and treats every affected layer.
Is the enzyme treatment safe for my pets?
Yes. Gemstone's methods are pet and child safe.
Should I clean the accident myself first?
Blot up what you can with a clean white towel and avoid scrubbing. If you used a product, tell us which one when you request your appointment.
