How do I remove throw-up stains from Berber carpet?

Answer: For vomit, I recommend generously and evenly spraying the area with a BISSELL enzyme action product such as BISSELL Pet Stain & Odor Pre-treat for Carpet & Upholstery.  It has enzyme action that goes deep into the carpet and "eats" away the stain.  Per instructions, spray the stain, and then cover with a damp towel for up to 72 hours. If any stain remains, generously and evenly spray the area with BISSELL oxygen based product such as OxyPro and let stand overnight. Repeat if needed.  Finally, use your BISSELL upright or portable deep cleaner over the affected area to remove all residues.
