Pet urine leaves both visible residue and odor-causing compounds that can remain after washing. The best approach is to remove moisture with cool water, use a fabric-compatible treatment, and avoid heat until both the stain and odor are gone.
Blot or rinse with cool water
For a fresh stain, blot with clean towels without rubbing outward. On washable fabric, a cool rinse from the back helps push residue out; very hot water can set odor and protein-based residue.
Use an enzyme treatment when the care label allows it
Enzyme cleaners formulated for urine can break down organic residue. Follow dilution and contact-time instructions and test dyed or delicate fabrics first; do not combine cleaning chemicals.
Wash with the correct detergent dose and enough space
After pretreatment, wash at the care-label temperature and leave enough room for water to circulate. More detergent does not guarantee less odor and can leave residue that holds soil.
Do not heat-dry until both stain and odor are gone
Smell the cleaned item and inspect it in good light before using a dryer. If the problem remains, repeat a compatible treatment; avoid ammonia-based cleaners because the similar odor can confuse or attract some pets back to the area.
