If you’re like most people, your utility sink has probably taken a beating over the years. One of the biggest culprits is paint splatter being left on the sink from cleaning paintbrushes. Fortunately it isn’t that difficult to remove.
Take WD-40 and lightly spray wherever the paint splatter and stains are. Let the WD-40 soak for 15 to 20 minutes. If the area is very large, or very thick, you might want to allow it to soak longer.
Once it is soaked, use a plastic scraper to gently scrape away the paint. If it stubborn, you may need to repeat the process once or twice. If you are left with paint stains, re-sprayed with WD-40 and use a nylon scrubber to scrub the stains away. You want to be careful not to use anything that is too abrasive, such as steel wool, as it can damage the finish on your utility sink, and can actually cause future stains to become trapped in the area.
After the pain is removed, give it a quick clean with regular dish soap and hot water, using a sponge on all the areas so you can remove the traces of WD-40 and paint. Now your utility sink should look much better.
