There is old human urine stains and smell in our house in the carpet what can we use to get the smell out and maybe a little of the stain help?
Answer: I suggest blotting up excess urine with a clean, absorbent cloth. Generously and evenly spray the area with a BISSELL enzyme action product such as BISSELL Pet Stain & Odor Pre-treat for Carpet & Upholstery. It uses enzyme action to go deep into the carpet and "eat" away the stain. Per instructions, spray the stain, and then cover with a damp towel for up to 72 hours. Then, use your BISSELL upright or portable deep cleaner over the affected area.
Finish with OxyPro® Stain Remover for Carpet, if there is any remaining discoloration. Treat it with the OxyPro® and let stand overnight.
