Quick answer
To get rid of cat pee smell on clothes, rinse the item in cold water, soak it in a white vinegar and water mix, then wash it with an enzyme laundry booster made for pet urine. Do not use hot water or the dryer until the smell is gone, because heat can set it in. Air dry, sniff-test, and repeat if you still smell it.
Free fix vs. permanent fix
Cold rinse, vinegar soak, baking soda wash
- Rinse in cold water straight away
- Soak 30 to 60 minutes in half white vinegar and half cold water
- Wash with detergent and half a cup of baking soda
- Air dry, sniff-test, and repeat if needed
How long it lasts: Works for fresh or light accidents. Dried urine leaves residue that water and vinegar do not break down.
An enzyme laundry booster for pet urine
Cat urine leaves residue that dries into crystals water barely touches, and detergent alone cleans only the surface. Enzyme cleaners are made to break down the residue that holds the smell. Added to a soak or the wash, a booster handles what vinegar and baking soda leave behind.
What to get: Enzyme laundry booster for pet urine
How long it lasts: The odor is removed, not covered, so a clean sniff test means it is out of the fabric.

Why it happens
Urine soaks deep into fabric
Cat urine is concentrated and sinks into the fibers. Detergent rinses the surface, but residue stays deeper in.
Crystals left behind as it dries
Dried urine leaves crystals that do not dissolve in water. They release their smell again when the cloth gets damp or warm.
Heat sets the odor
Hot water and the dryer bake the residue into the fibers. That is why clothes can seem fine wet and come out of the dryer smelling worse.
Scent that only masks
Fragranced detergent and fabric softener cover the odor for a day. Then it returns, sometimes mixed with the perfume.
Ammonia-type cleaners
Urine already contains ammonia, so ammonia-based cleaners smell like urine and can draw a cat back to the spot.

-
Sniff-test while damp, then air dry
Smell the item while it is still damp, since odor shows most when wet. Hang it to air dry. If any smell remains, repeat the booster step. Keep it out of the dryer for now.
-
Treat the spot where it happened
Tool used: Enzymatic pet odor spraySpray the bed, rug or floor spot with an enzymatic cleaner and let it dry, so the cat is not drawn back to the same place.

When free fixes aren't enough
If the smell survives two enzyme washes, the urine may have soaked into padding, a mattress or carpet, and the clothes are not the only source. Silk, wool and dry-clean-only items should go to a cleaner, and tell them it is pet urine. If your cat keeps peeing on clothes or beds, book a vet visit, because sudden accidents can signal a urinary infection or stress. If a male cat strains with little or no urine, it is an emergency, so go to a vet right away.
