Stain removal is all about speed and technique. Here's the proven method for tackling urine stains effectively.
Blot up as much urine as possible with paper towels or a clean cloth. The more you absorb now, the less stain remains.
Enzyme cleaners specifically designed for urine break down the proteins that cause stains and odors. Saturate the area.
Allow the enzyme cleaner to work for the time specified on the bottle (usually 15 minutes to several hours).
Blot up the cleaner and rinse with cold water. Blot dry.
Once dry, sprinkle baking soda over the area to absorb any lingering odor. Vacuum after several hours.
