The bathtub is often the largest item in the bathroom and it's hard to miss it when you walk in there. If your bathtub is splattered with paint splotches or has a tired-looking paint job, you can remove them quickly and easily. All it takes is the right product and a little elbow grease.
To remove latex paint splatters from a bathtub, use a product called Goof Off according to the manufacturer's instructions.
Another way to remove latex paint splatters is with acetone nail polish remover or denatured alcohol and a cotton swab or soft cloth. Rub with gentle pressure and wipe clean with a clean, soft cloth.
Remove oil paint splatters with paint thinner and a cotton swab or soft cloth. Use gentle pressure to rub splatters and wipe clean with clean, soft cloth.
Try scrubbing off the paint with a Mr. Clean Magic Eraser (find them in the cleaning supplies section of the supermarket).
To remove paint from a bathtub that has been repainted, apply a specialized chemical paint remover, such as Peel Away 7, according to manufacturer's instructions. Cover adjacent surfaces---floors, walls, tiles—with protective plastic and masking tape.
Hire a professional refinisher to strip the paint and re-seal the bathtub.
