Remove Pet Odor Left by Previous Tenants (5-Step Guide)

How to get rid of pet smell from previous tenants?

Old pet odor usually lingers because oils, dander, and urine salts soak into soft materials and even the subfloor. To truly remove the smell (not just cover it), work from the source outward: find hotspots, deep-clean surfaces, and treat porous areas that keep releasing odor when humidity rises.

1) Find the odor “map” before cleaning

Start by sniff-testing room by room with windows closed. If you suspect urine, use a UV flashlight at night to locate stains on carpet edges, baseboards, and corners. Mark spots with painter’s tape so you don’t miss them once cleaning begins.

2) Wash what can be washed—and do it hot

Launder curtains, removable cushion covers, throw rugs, and any washable fabric using the hottest safe setting. Add an odor-fighting booster if needed, then dry thoroughly. Lingering dampness can revive musty-pet smells.

3) Clean hard surfaces with a degreasing approach

Pet oils cling to walls, trim, doors, and floors—especially near where animals rubbed or slept. Wipe down baseboards and lower walls with a gentle degreaser or all-purpose cleaner, then rinse with clean water. Don’t forget vents, fan blades, and the inside of closets where smells can settle.

4) Treat carpets and padding the right way

For carpeted areas, vacuum slowly with a HEPA filter first. Next, use an enzymatic cleaner on urine-marked areas (follow dwell time directions so enzymes can break down residues). If the odor returns after drying, the contamination may be in the pad or subfloor—at that point, pad replacement or sealing the subfloor can be the lasting fix.

5) Refresh the air without masking

After surfaces are cleaned, run an air purifier with activated carbon and replace HVAC filters. Ventilate strategically: open windows while running fans to exhaust stale air. Avoid heavy fragrances early on—they can combine with remaining odor and make it harder to tell what’s working.

FAQ

What’s the best way to remove pet odor from carpet without replacing it?

Vacuum thoroughly, then apply an enzymatic cleaner to any urine-affected spots and let it sit for the full recommended time before blotting and drying. If smells persist after drying, the padding or subfloor likely needs treatment or replacement.
