How to Remove Tar From a Bathtub

Apply a paint, oil and grease remover to the tar and let it set for 10 minutes. Put on rubber gloves and use a cleaning solvent, available at hardware stores, to clean the remover from your tub.

Mix 1 tsp. of mild dishwashing liquid that has no alkalis or bleach into 1 cup of warm water. Apply the solution to the tar and rub it with a clean, soft rag.

Spray the tar with a laundry pre-wash spray such as Spray and Wash or Shout. Let it set for 10 minutes. Then wipe it from the tub with a clean rag.

Dab mayonnaise onto the tar to loosen it. Wipe the tar away with a soft rag.

Spray WD-40 on the tar, working with one small section at a time. It contains petroleum distillates that remove grease, tar and adhesives. Let the WD-40 soak into the tar for ten minutes. Then gently scrape the tar from the tub with a plastic scraper to avoid scratching your bathtub. Wipe the WD-40 with an absorbent rag. Then clean the bathtub with Soft Scrub to wash away all the slippery WD-40. Rinse the area with cold water.
