Removal of pet urine?

Answer: The BISSELL line of pet- friendly products will be perfect for this stain!  For your urine stain, blot up the excess liquid with a clean, absorbent cloth. Then generously and evenly spray the area with a BISSELL enzyme action product such as Pet Stain and Odor Pre-treat for Carpet and Upholstery.  It has enzyme cleaning agents that go deep into the carpet and "eats" away the stain.  Per instructions, spray the stain and cover with a damp towel for up to 72 hours.  Then, use your BISSELL upright or portable deep cleaner over the affected area.
