Permanent markers are known for their staying power, but there are several effective methods to remove them from countertops. These include using rubbing alcohol, acetone, or WD-40. The best method will depend on the type of countertop material.
It is important to test any cleaning solution in an inconspicuous area first to ensure that it does not damage the countertop. Once you have found a solution that works, apply it to the permanent marker stain and allow it to sit for a few minutes. Then, wipe away the solution and the permanent marker stain should be gone.
