What to Use on Different Bathtub Materials

The steps outlined above are general directions on how to clean a bathtub. Each cleaning method mentioned may not work for all types of bathtubs. Here are a few popular bathtub materials and suggestions on what you can and shouldn’t use on them.

Fiberglass Bathtub

When cleaning a fiberglass bathtub, use non-abrasive products. Never use a scouring pad, scrubbing powder, stiff wire brushes or bleach as these could cause damage to the bathtub. It’s safe to use vinegar, dishwashing liquid, baking soda, hydrogen peroxide and cleaners made specifically for fiberglass.

Acrylic Bathtubs

Avoid using abrasive cleaners and abrasive materials including scrubbing powder, scouring pads, etc. when cleaning an acrylic bathtub. Also steer clear of bleach, ammonia or cleaners containing ammonia. It’s safe to use dishwashing liquid, baking soda, vinegar, borax, cream of tartar, hydrogen peroxide and cleaners made specifically for acrylic.

Porcelain-Enameled Bathtubs

Vinegar and bleach are acidic chemicals that could damage porcelain-enameled bathtubs. Use microfiber cloths or soft sponges when cleaning. Even though it’s an abrasive, it’s safe to use baking soda in paste form provided it’s diluted well. It’s also safe to use ammonia, shampoo, hydrogen peroxide, dishwashing liquid and cleaners made specifically for porcelain-enameled bathtubs.

Cast Polymer

Avoid using abrasive cleaners, scrubbing sponges, scouring pads, etc. A vinegar/water mixture works well on a cast polymer tub. It’s safe to use white vinegar, baking soda, mild detergent soap and cleaners made specifically for cast polymer.

Bathtub Cleaning Tips

It’s not difficult to keep your tub clean and free from germs. To keep it as clean as possible, follow these tips:

  • Wipe the tub down after every shower or bath taken. This will help remove excess moisture that could lead to the development of soap scum and mildew.
  • After every shower, use a squeegee on the walls and shower door.
  • If your bathroom has an exhaust fan, turn it on while showering or taking a bath.
  • Once or twice a week, use a spray bottle filled with white vinegar (which is a natural cleaner) to spray down the tub, walls, shower door or curtain and tub.
  • Plan to deep-clean the bathtub at least once a week if you use it regularly. If you don't use your tub regularly, aim to deep-clean it once every two weeks or so.
  • Clean any mildew growth with a bleach-based product as soon as you see it. This could reduce the risk of it spreading.

Customers usually have questions about cleaning their bathtubs. Below are just a few.

What is the Best Way to Clean a Bathtub?

Some people tend to stick with bathtub cleaners purchased from the store, while others depend on their tried-and-true home remedies. Experiment with the ways we've outlined in this guide to find the bathtub cleaning method that's right for you.

What Cleans a Very Dirty Bathtub?

Should You Use a Brush to Clean a Bathtub?

A soft-bristle brush can be used on a bathtub for getting into tight corners and edges of the tub. Although bathtubs are made of strong, durable materials, it's not recommended to use a firm-bristled brushed because it can actually damage the bathtub.

To brighten a dull bathtub, try using hydrogen peroxide. It doesn’t have the odor of bleach, but it works as a natural bleaching agent.
