How to Clean Dog Vomit Out of Carpet
Dog vomit on carpet or a rug is a mix of solids and liquid, so the order of steps matters. This guide covers lifting the solids, blotting, treating the stain, rinsing and drying, using what the Carpet and Rug Institute (CRI), the IICRC and the AKC say.
Act quickly
The CRI's Spot Solver entry for vomit opens with: "Act Quickly! Delaying may cause the spill to become a permanent stain." The IICRC, which certifies carpet cleaners, explains why:
"The longer vomit stays in contact with your carpet or upholstery, the more likely you are to have staining and lingering odor issues."

Step 1: Remove the solids first
Lift, do not push. The CRI says:
"Gently scrape up semi-solids with a rounded spoon. Break up solids and vacuum."
The IICRC's first step is the same: "Remove as much solid matter as possible." If you have one, the IICRC adds: "Use a wet/dry vacuum to extract as much vomit as possible prior to any spot cleaning attempts."

Step 2: Blot the liquid, do not rub
The CRI says: "Blot liquids with a dry, white absorbent cloth or white paper towels." Its general spill advice explains the white cloth and warns against scrubbing:
"Using a printed or colored material may transfer ink or dye to your damp carpet. Continue blotting until the area is nearly dry."
"Warning: do not scrub or use a brush. Bristles and scrubbing can damage carpet. Fraying and texture change are the likely results."

Step 3: Test a hidden spot
Before any solution touches the stain, the CRI says:
"Pretest any spot removal solution (for color transfer to the cloth or damage to the carpet) in an inconspicuous area. If a change occurs, select another solution."

Step 4: Treat the stain
The IICRC's home steps for vomit are:
- "Blot the area (if still moist from the spill) with a dry absorbent cloth."
- "Blot with a cloth dampened with clear water. Microfiber cloths are ideal for this purpose."
- "If the stain remains, mix a few drops of liquid dish soap with a cup of water in a spray bottle and mist onto the area, and blot."
- "Repeat until the stain disappears, making sure to blot between each application."
The CRI's detergent solution is similar: "Mix one fourth (1/4) teaspoon of a liquid dish washing detergent per one (1) cup of lukewarm water." It also says "Never use a laundry detergent of any type". On how to apply a solution, the CRI says: "Allow to remain on the spill a few minutes. Be patient. Blot." and "Complete removal may require repeating the same step several times."

Step 5: Rinse and blot dry
Do not leave cleaner in the carpet. The CRI says:
"When the spill is completely removed, rinse the area with cold water; blot with a dry cloth until all moisture is removed."
"Thorough rinsing is necessary to remove detergent residues that may cause rapid soiling."
To avoid soaking the spot while you rinse, the CRI adds: "A mist type sprayer is recommended to prevent overwetting."

If a smell stays
Vomit can reach below the surface. The IICRC says: "Due to vomit's liquidity, your carpet pad or upholstery cushions may need subsurface treatments and possible disposal." For pet messes in general, the CRI suggests you "Use CRI Certified Seal of Approval cleaning products that are specifically designed for pet stains and odors."

What to avoid
- Rubbing or brushing. The CRI vomit steps say to "work in gently" and to work "from the edges of the spill to the center to prevent spreading."
- Steam and heat. The CRI vomit steps rinse with cold water. The CRI's steam warning is written for urine: "Don't use a steam cleaner when dealing with urine spots because the heat will set the stain and the smell."
- Too much product. The CRI says: "Never use any of the solutions in concentrations stronger than those recommended."

Wool and delicate rugs
Check the rug's label first. For valuable rugs, the CRI says:
"Clean imported rugs according to the carpet manufacturer's specifications or use a professional cleaning service. Be gentle with fringe. For heirloom-type rugs, hire professionals."
The IICRC's vomit steps end with a hydrogen peroxide step for leftover color, which we leave out here. Its note on that step: "Not recommended for wool or other natural fibers without extensive testing for possible color loss." On rug dyes, the IICRC's area rug sheet says: "Pre-testing of suspicious colors and rapid drying before cleaning can help avoid potential rug damage."

When to call a professional
The IICRC says: "If these procedures do not work, call your IICRC Certified Professional Cleaner." The CRI explains: "Professional cleaners have the ability and the equipment to use more aggressive cleaning solutions to remove stubborn spills."
