To achieve removal of vomit stains and related odors, it is important to address these types of problems as quickly as possible. For vomit stains, you will need your BISSELL Carpet Cleaner, warm water (not hot), enzyme producing bacteria detergent (BISSELL Pet Stain and Odor Remover), and clean white paper/cloth towels. If the vomit stain has a lot of solid material, remove the excessive material with a blunt spoon or spatula. After the excess material is removed, use your BISSELL Carpet Cleaner to rinse and extract the stain. Next, apply an enzyme producing bacteria detergent to the stained area. BISSELL Pet Stain & Odor Remover is an effective and easy to apply enzyme producing bacteria detergent. After applying an enzyme producing bacteria detergent, place clean, white, damp, paper/cloth towels over the treated stain, and let the enzyme producing bacteria detergent interact with the stain for 3-5 hours. After 3-5 hours, rinse with warm water. Remember it is very important not to over saturate your carpet. Use your BISSELL Carpet Cleaner to rinse your carpet. Use a fan to expedite the drying process.
