How to Whiten a Yellowed Fiberglass Bathtub

A yellowed fiberglass bathtub can be unsightly and make you feel embarrassed to have guests over. This discoloration is often caused by the buildup of hard water minerals, dirt, and soap scum. Over time, these can stain the surface of the bathtub, making it difficult to clean and restore its original color.

However, there are several effective methods you can use to whiten a yellowed fiberglass bathtub and bring back its pristine appearance. Here are some of the most common and effective methods:

1. Baking Soda and Vinegar

This is a natural and inexpensive way to clean and whiten your fiberglass bathtub. Simply sprinkle baking soda over the surface of the tub and let it sit for a few hours, or overnight. Then, scrub the bathtub with a sponge or brush dampened with vinegar. The baking soda will help to neutralize the acids in the vinegar and create a fizzy reaction that helps to lift stains and dirt. Rinse the tub thoroughly with water and dry it with a clean towel.

2. Hydrogen Peroxide

Hydrogen peroxide is a strong oxidizing agent that can help to bleach away stains. Apply hydrogen peroxide to the yellowed areas of the bathtub and let it sit for 30 minutes to an hour. Scrub the tub with a sponge or brush, rinse it thoroughly with water, and dry it with a clean towel.

3. Commercial Fiberglass Cleaner

There are several commercial fiberglass cleaners that can be used to whiten and brighten your bathtub. These cleaners typically contain mild acids or bleach, which can help to remove stains and discoloration. Follow the instructions on the cleaner label carefully, and be sure to wear gloves and ventilation when using these products.

4. Professional Bathtub Refinishing

If the yellowing of your bathtub is severe, or if you have tried the above methods without success, you may want to consider professional bathtub refinishing. This process involves removing the old finish from the tub and applying a new one, which can restore the tub's original color and shine. Professional bathtub refinishing is a more expensive option, but it can be a good investment if you want to restore your bathtub to its former glory.
