If you simply can't remove paint stains that have dried out, the best thing to do is to contact a professional carpet cleaning service. Since dry paint on the carpet is the worst case scenario, let's focus on how to remove stains from oil- or water-based paint. If you spilled acrylic paint, you will need to use a combination of detergents. Start by soaking the paint with laundry detergent.
Then, apply acetone to break down the paint. Continue to apply a carpet cleaning solution and then scrub the paint with a scrub brush. If acetone doesn't remove all of the paint, you can use a commercial carpet cleaner as the next step. However, do your best to rinse off the acetone before applying the cleanser.
If you spill a little paint during your next home improvement project, don't panic. Many paint stains, both oil-based and water-based, can be removed from carpet fibers with a little patience and a few cleaning products. Just be sure to deal with these carpet stains right away and then move on to other tasks, such as removing paint from clothes or cleaning brushes. When the oil stain has disappeared, clean the carpet as if you were removing a water-based paint (see above) to remove any remaining turpentine.
If, despite all your efforts, there is still some paint residue left, don't hesitate to try a commercial carpet cleaner. Keep in mind that turpentine is strong and can discolor the carpet if you pour it too much all at once. Now that the dried paint has softened, gently scrape it off the carpet fibers again, little by little. Cleaning dry stains or paint spread over a large area requires the use of professional equipment and methods.
Embassy Cleaners has been providing top-notch cleaning services since 1937 to the casual and couture markets. Avoid rubbing the stain, as this can cause the paint to penetrate deeper into the carpet fibers and make it impossible for it to come out. But the good news is that, most of the time, you can remove paint from the carpet with just a handful of everyday household items. Your carpet now contains a lot of liquids, which can ruin your machine if it doesn't have a waterproof interior.
To avoid discoloration, read carpet care guidelines to avoid using strong cleaning agents or simply try them on the other side of the carpet that is hidden.
