Rust Stains on a Fiberglass Bathtub: How to Eliminate Rust Spots from a Fiberglass Bathtub?

Make a mixture with vinegar and borax and scrape with a toothbrush to eliminate rust spots from a fiberglass or acrylic bathtub.

Even if the windows are closed to block out air, rust spots may stain your fiberglass or acrylic bathtub; it’s the oxygen in the water that performs the dirty job. The spots are most often spotted under the faucet’s nozzle and handle, but they may also develop around any metal object, such as a soap dish. 

They’re often accompanied by golden scale deposits caused by mineral deposits in the water. These spots can be removed without the use of a strong cleaning, however, there’s nothing stopping you from doing so if you desire. All you’ll need is a toothbrush and a few common household items.

Steps of removing rust spots on fiberglass tub:

  • Combine full-strength vinegar and borax to make a paste. Although some cleaners have had success combining vinegar and sodium bicarbonate, the mixture rapidly loses its effectiveness when the acidic vinegar interacts with the alkaline baking soda. Because vinegar does not react with borax, the paste will last longer.
  • Apply a liberal amount of the paste to the spots and scrape with a toothbrush. If you leave the mixture on for several minutes before cleaning, certain stubborn spots may be simpler to eliminate. Allow it to dry before spraying it with additional vinegar if it becomes powdery.
  • Rinse well with clean water. If any discoloration persists, spritz them with full-strength vinegar and clean them again.
  • As an alternative to vinegar, spritz or put hydrogen peroxide on the spots, then rub or scrape them away with a gritty sponge or a toothbrush. Some commercial spot removers with h2o2 as the principal component are a safe and efficient substitute for pure peroxide.

Borax
