How to Restore Shine to Fiberglass Shower: Methods

Stepping into a dull, grimy shower will leave you feeling not as fresh as you intended. Fiberglass tops the list of most affordable materials to have on your tub. This makes it a preference in most households. When well-maintained, they are appealing and durable.

Clean fiberglass surfaces weekly with a mixture of 1 cup water, 1 cup vinegar, and 1 tablespoon of dish soap. Spray the mixture to the surface then wait for 15 minutes before scrubbing gently. You can also refinish or repaint the fiberglass shower surface if cleaning doesn’t restore it.

Scratches on the tub while cleaning with the wrong tools will ruin its shiny appeal. However, constant cleaning and care can eliminate other common stains such as soap scum and grime. Learn how to restore the shine on your fiberglass shower tub by applying the tips below.

Is my bathtub made of fiberglass?

First, you need to be absolutely sure that you are dealing with fiberglass. Here is how to tell your shower tub is made of fiberglass.

1. Weight

Fiberglass, unlike other common materials used for the shower, is lightweight. You can easily touch and tell from the thin edges. 

2. Scratches Effortlessly

Fiberglass will scratch easily, forming crevices that the grime and other dirt stick on to give it a discoloration.

3. Pales Fast

Fiberglass tends to fade fast from a whitish shiny appeal to a yellow shade. 

4. Few Design options

Most fiberglass shower tubs are basic in style, details and design. This is attributed to the complexity of the manufacturing process.

5. Few Colors

Fiberglass is commonly white. If your tub is white, you are highly likely to be dealing with fiberglass. In addition, fiberglass is commonly mistaken for acrylic, which has many colors.

6. Warping

After some time, fiberglass tends to warp, given its porous nature. In addition, the constant exposure to dampness makes the water infiltrate, affecting the shape and texture of the tub.

7. Smooth Finish

You may fall into the trap of confusing fiberglass with acrylic. The most striking difference is that acrylic has a stronger solid feel while fiberglass has a smooth finish.

How to Restore Shine to Fiberglass Shower

Here is how to restore a fiberglas tub or other fiberglass surface:

1. Clean Routinely

The best way to clean a fiberglass shower is to do it routinely to prevent the accumulation of dirt which takes away it shine.

For your routine cleaning, ensure you have soap, baking soda and water

Follow these steps for your cleaning process:

  • Apply baking soda on the entire shower tub, especially on any stained sections.
  • Allow the baking soda to sit for a few hours.
  • Rub the glass with a wet piece of cloth or sponge.
  • Wash with soap.
  • Rinse with clean water.

This should renew the look of your fiberglass shower, leaving it sparkling clean.

2. Use Vinegar

White vinegar comes in handy in cleaning most households and is one of the best cleaners for fiberglass showers.

To properly clean with vinegar, arm yourself with white vinegar, water, a spray bottle and a sponge then follow these steps:

  • In its acidic form, pour the white vinegar into a spray bottle.
  • Spray the entire tub, including the cracks and crevices visible.
  • Allow the vinegar to sit for half an hour.

If the fiberglass doesn’t regain its shiny status, you can go further and rub the tub with baking soda after the vinegar. Then rinse. This should do it.

Homemade Fiberglass Tub Cleaners

You don’t have to break the bank to buy expensive tub cleaners. Instead, improvise them at home, and they’ll work out just as fine.

Here is how:

1. Vinegar and Liquid Soap

Get the liquid soap of your choice and mix it with vinegar at a 50:50 ratio then spray the solution on your shower tub. Ensure you get to every corner and crack on your tub.

Scrub it off gently after you have allowed it to sit for 30 minutes. Rinse with clean water until the tub sparkles. Repeat the process until you are satisfied with the results.

2. Ammonia, Vinegar and Baking soda

This combination is meant to eliminate the most stubborn stains on your shower tub.

You need to have ⅓ cup of ammonia, half of baking powder, and half of the white vinegar then follow these steps:

  • Get a spray to combine the solution with around 5 cups of water.
  • Ensure you spray on every corner of the tub, including all the crevices.
  • Let the solution sit on your tub for half an hour.
  • With clean water, rinse the tub.

If the glass doesn’t shine with these steps, repeat the exercise until you get the desired results. This should restore the sparkle in your bathroom.
