Before you use detergent, soap, or bleach:
- If its carpet or furniture, blot firmly with a towel to soak up as much as you can, then spritz with water, then repeat a few times (blot/spritz), followed by a heavy spray of an enzyme product such as Nature's Miracle. Cover with plastic to keep the enzymes moist and thus active.
- If its a washable item, rinse out as much as you can with water, wring it to remove excess water, then douse it in an enzyme product such as Nature's Miracle and put aside in bucket or wrapped in plastic to keep the enzymes active.
Wait a good day to let the enzyme product work.
Uncover/unwrap and repeat the appropriate preceeding process, or then use another cleaner of some sort if the odor seems to be eliminated.
I did this with an apartment carpet that a former tenant's cats had saturated with pee, all around the perimeter. Rolled back the carpet, treated the back of it, covered in plastic, and 2 days later, odor much improved and less likely to come up during high humidity (thank goodness!).
