Fiberglass tubs can be vulnerable to scratches, but if you use the right cleaning products, it's easy to keep your tub looking clean. We'll even show you how to get tough stains out of a fiberglass tub without scratching, so keep reading!
Steps
-
Mix 1 quart (0.95 liters) of warm water with ½ cup (125 mL) of detergent. You can use a dishwashing or liquid laundry detergent. Mix the ingredients together until they are well combined. [1] X Research source
- Avoid abrasive cleansers like scouring powders.
-
Rinse the tub with water. Use a bucket or a pitcher to rinse your tub. Make sure all of the surfaces that you want to clean are wet.
- Alternatively, if you have a removable shower head, then you may use this to rinse your tub.

Apply the solution with a sponge. Use a circular motion to scrub the tub with the sponge. You can use a toothbrush to clean small crevices.
- Make sure to use gentle applicators like sponges, cloths, and scrub brushes made from polyester, polyethylene, or nylon. Abrasive applicators like steel wool and scouring pads will scratch your fiberglass tub.
-
Rinse the tub thoroughly. Use a bucket or a showerhead to remove all traces of residue and soap. You may need to rinse your bathtub three to five times. [2] X Research source
-
Dry the tub with a towel. This way you can prevent water from pooling in the corners and crevices of your tub. Pooling can cause mildew, mold, and bacteria to grow. [3] X Research source
- Drying the tub will also prep it for polishing, if you choose to polish your tub.

Mix 3 parts baking soda to 1 part water to form a paste. Make sure the paste is thick, similar to the consistency of toothpaste. You want the paste thick enough so that it can stick to the sides of your tub. [4] X Research source
- For extra cleaning power, add in 2–3 tablespoons (30–44 mL) of vinegar.
- If your paste is thin, then just add more baking soda until it forms a thick paste.
-
Apply the paste with a sponge. Apply the paste to both the sides and bottom of the tub. Then let the paste set for 30 minutes. [5] X Research source
- Depending on how dirty your tub is, you may need to let the paste set for a longer amount of time, like an hour or so.
-
Scrub the paste off. Do this once the paste has set for the allotted time. Use a nylon brush to scrub the paste off to avoid scratching your tub. [6] X Research source
-
Rinse the bathtub with water. Using a bucket or a showerhead, make sure to rinse it thoroughly until the residue is gone. Then dry your tub with a clean towel. [7] X Research source
-
Remove tough stains with nail polish remover. Dip a cotton ball or a clean, white cloth in the nail polish remover. Gently rub the tough stains individually until they are gone. Wipe the areas with a clean, wet cloth, and then dry them with a clean towel.
- Alternatively, you can use turpentine to remove tough stains.
- Because these solvents are highly flammable, do not use them near open flames or heat, and make sure the area is well-ventilated.

-
Apply a marine-grade rubbing compound with a soft cloth. Working in small sections, apply the compound onto the sides of your tub, paying special attention to dull spots and scratches. [8] X Research source
- Do not focus on one area for too long. The compound may burn the fiberglass if you do.
- You can purchase the marine-grade compound from your local hardware or automotive store, as well as online.
-
Buff each section with a terry cloth. Do this right after applying the compound. Using a circular motion, rub the sections with the cloth to buff them. [9] X Research source
-
Apply a car wax in small sections with a soft cloth. Any type of car wax will work, however, apply the wax per the instructions on the bottle. Make sure the wax gets inside small crevices in the tub. [10] X Research source
- Try to avoid applying wax onto the bottom of your tub. The wax will make your tub very slippery. If you do use wax on the bottom of your tub, make sure to place a bathmat in the tub afterwards to avoid slipping.
-
Rub the sections with a terry cloth in a circular motion. This will buff the wax. Rub the sections until all of the wax is removed and the surface shines. [11] X Research source
-
Rinse the tub with cold water. Use a bucket or a showerhead to do this. Rinse your tub 2 to 3 times. Then, dry it with a clean towel. [12] X Research source
- Make sure to use cold water so the wax will harden.
- It is recommended that you polish your fiberglass tub twice a year.
