So, you purchased a new bathtub or thinking about purchasing one. Owning a bathtub is not just all about relaxing and having a good “me” time in the bathroom. It also comes with a responsibility – keeping the bathtub clean at all times. And the type of cleaning methods vary depending on the type of material your bathtub is made of. So, here is a list of bathtub materials and how you should be cleaning them.

Porcelain enamel

Bleaching is not allowed for bathtubs made out of porcelain enamel since it can cause discoloration. You should also avoid using white vinegar and scouring powder as cleaning materials since they can damage the bathtub’s finish. Abrasive cleaners are also not suitable for porcelain bathtubs because they are strong enough to chip the surface of the tub.

We have a homemade porcelain bathtub cleaner solution that you can use once a month on your tub. All you need is a gallon of hot water and four to six tablespoons of dishwashing soap. Then, apply the mixture on the bathtub’s surface with a rag. Gently scrub to clean and rinse with water. For a shiny finish, rub the sides of the bathtub with a small amount of lemon oil.



Chemical and abrasive cleaning materials can easily damage the acrylic plastic material of the bathtub so extra care is needed for this type of tubs.

To clean an acrylic bathtub, wet the bathtub with warm water first. Then, use a small amount of baby shampoo on your rag and use it to rub the bathtub’s surface. Rub in circular motions. Rinse and repeat if necessary. Once you are satisfied that the bathtub is clean, wait for it to dry. When the surface is completely dry, apply a small amount of car wax to a rag and rub it on the surface in circular motions. Let the wax dry out then buff with a dry cotton ball.


Fiberglass bathtubs are less durable compared to other materials. Fading is expected with constant use and the surface can easily crack and be scratched.

For this sensitive material, you can use this homemade cleaning solution. Mix baking soda and one half cup of dish soap in hot water. This will form a paste once you mix them. Keep adding baking soda until it is thick enough to stick on the wall of the bathtub. Then, use a sponge and apply on the bathtub. Let it sit for 30 minutes. After, scrub the bathtub. Rinse with cold water and wipe the surface with a paper towel. If there are stubborn stains remaining, use a magic eraser to wipe them off.

Enameled Cast Iron

This is one of the most expensive types of bathtubs that you can get in the market. Although very durable, you still should avoid using cleaning products with strong chemicals because this can cause discoloration.

You can make a paste out of warm water and baking soda. Apply the paste on the stains and let it stay there for about half an hour. After, use a clean towel to scrub off the dirt and stains. Use warm water to rinse. If there are stubborn stains remaining, you can repeat the process again but replacing baking soda with a teaspoon of trisodium phosphate (TSP) cleaner.

Cast polymer (granite or marble)

These materials are made out of natural stone that are engineered to be molded with other materials. Proper care is important as it is very prone to scratches. It is recommended to avoid cleaning products that use harsh chemicals and using scratchy sponges while cleaning.

To clean this type of tub, you can use a mild detergent or soap. If you see soap scrums, you can get rid of them by mixing equal amounts of water and vinegar and spraying it on the affected area before wiping it clean.

Remember to always check your cleaning products to ensure that they are safe for the material of your bathtub bunnings. Cleaning with products that are not meant for the job does not only mean you are wasting time and effort but also causing damage to the tub’s material.
