Cleaning an acrylic bathtub is easy as long as you use the right products. Acrylic scratches easy, so it is not a good idea to use a scouring pad or hard brush. Chemical cleaners with solvents can damage the acrylic, eventually causing it to crack. To safely clean it, follow these steps. Step 1 - Preparation. Remove everything from your tub, such as shampoo bottles and soap, wiping off the bottoms to remove any soap scum. Now is a good time to clean items that you use in your tub. If you have a loofah or shower sponge, place them in your sink in warm water with a little shampoo or dish liquid. Step 2 - Cleaning the Inside. To clean the inside of the acrylic bathtub, fill it with warm water and add 3 or 4 squirts of dish liquid. Allow it to sit for 30 minutes. Let the tub drain and use your sponge to wipe away the residue.
