Paint thinner is a solvent with a distinctive chemical odor. Solvents usually will not do the carpet any damage, but the smell may linger and cause toxic fumes. The smell will evaporate in time, but will cause discomfort if you want to sit in the room. You can produce an effective carpet deodorizer that will remove the paint thinner smell and freshen the carpet. The mixture does not take long to produce, and is nontoxic.
Blot the paint thinner with a white absorbent cloth. The cloth needs to be white to avoid color transfer to the carpet.
Mix 2 cups baking soda with 10 drops of an essential oil of your choice.
Sprinkle the baking soda and essential oil mix onto the carpet, concentrating on the paint thinner stain. Baking soda is a natural cleaner and deodorizer that will absorb dirt and odors. Essential oil adds a fresh fragrance to the carpet.
Leave the baking soda and essential oil to sit in the carpet for at least one hour. You can leave it overnight if possible to absorb the solvent odor.
Vacuum the carpet thoroughly, concentrating on the paint thinner stain.
