Rit dye is ideal for dyeing clothing, drapes and other fabrics, but it can also be messy to work with. Even though you try your hardest, sometimes the dye might end up where you don't want it, like on your carpet. Whether the dye is blue, red or green, you likely don't want the spot to be a permanent part of your carpet. Remove Rit dye from carpeting the right way so the dye doesn't spread and the carpeting remains intact.
Pour 2 cups of warm water into a clean container. Mix in 1 tablespoon each of vinegar and dish soap.
Dab the soapy vinegar mixture onto the Rit dye stain with a clean rag. Blot the carpeting with a dry rag to soak it up. Continue doing this until the dye is no longer coming from the carpet onto the rag.
Flush the spot with clean water. Absorb the water with a dry rag.
Dab rubbing alcohol onto the spot with a clean rag. Blot to dry. Sponge with more alcohol and let the spot air-dry.
Rinse the carpet with a rag and cold water. Soak up the water with a clean, dry rag.
Combine 2 cups of warm water with 1 teaspoon each of household ammonia dish soap. Dab this solution onto any remaining Rit dye left on the carpet. Sponge more of the cleaning solution onto the stain every five minutes. Do this for 30 minutes, then rinse with cold water and dry thoroughly with a clean rag.
