Tomato sauce, whether from pasta sauce or juice, is tricky to remove once it has spilled on upholstery. As with any type of stain, the best procedure is to act fast and try to remove the stain right when it happens, rather than after it dries and sets. When using a new cleaning technique on a couch or chair, try it first in a small corner to make sure it does not destroy the fabric before using it on a main area.
Things You'll Need
Liquid dishwashing soap
Measuring cups and spoons
Clean white rag
Use a clean bucket to mix 1 tbsp. liquid dish washing soap and 2 cups water. Mix to combine.
Dip a clean white rag into the cleaning solution and ring it out. Saturate the stain using the cleaning solution. Do not saturate the upholstery padding, but make sure the stain is wet.
Blot up the stain and cleaning liquid using an up and down motion. Do not scrub the stain with the solution, use a gentle up and down motion to blot only. Fold the white rag after each blot to prevent the tomato sauce on the rag from spreading further on the upholstery. Continue to blot until the stain is removed.
Repeat the process by adding the cleaning solution and water to the stain and blotting up again until the entire stain has disappeared.
Wet a clean sponge under cool water. Ring out the sponge completely and blot up the cleaning liquid from the upholstery.
Blot dry the spot using another clean white rag. Allow the upholstery to air dry before use again.
