The steps for how to remove glue from a stainless steel sink are simple. We recommend you wear gloves for this process. First, soak a cotton ball in acetone-based nail polish remover. Hold the cotton ball onto the glue. You should allow the acetone to soak into the glue for 5-10 minutes. As it begins to come loose from the surface of your sink, simply use a plastic scraper to remove the glue.
