 Tips on Cleaning Fiberglass Shower

Tips on Cleaning Fiberglass Shower

Cleaning a fiberglass shower stall can be daunting. Dirt, mildew, and soap scum can quickly accumulate in the enclosure if it’s not properly cleaned or maintained. However, there are simple ways to clean your shower stall, like:

  • Check that it’s really fibreglass. Your tub or shower stall might be made of acrylic, porcelain, or enamel. Knowing for certain what the material is will help you choose the proper fibreglass shower cleaner,
  • Identify the type of stain. There are a lot of things that can cause a stain, from soap scum to bath bombs and hair products. When you know what caused the stain, you can then identify what cleaner or method to use to clean it.
  • Wipe down the stall while it’s still warm. Most shower stains are the result of organic dust, cleaning products, and sebum. These are usually soft and easy to scrape off in warmer temperatures. It’s a good idea to clean them after your shower. If not, you can run the water at its hottest for about five minutes until the bathroom is warm and steamy. Then you can scrub and wipe down the stall. You can also heat your cleaning agent in the microwave but read the instructions carefully first.
  • Ditch the abrasive pads. While our instinct is to scrub and scrape off scum, dirt, and grease, that doesn’t work well with fibreglass. Using abrasive pads, steel wool, and rough scrubbers will only result in unwelcome scratches. It’s best to stick with soft cloth or sponges.
  • Drop the bleach. High concentrations of this chemical is bad for your skin, lungs, and eyes. It’s also terrible for your fibreglass shower. You’re better off using ammonia, baking powder, or good, old-fashioned vinegar.

How to Make Your Old Fiberglass Bathtub Or Shower Look Brand New

Your fiberglass bathtub or shower will start to look its age at some point. The minuscule scratches on its surface will accumulate grime and dirt, resulting in dark spots and stains.

Apply the mixture to the walls or floors of the fiberglass shower or tub using a sponge. Let it sit for about half an hour before scrubbing. Rinse the enclosure or tub with cold water. Wipe it dry with a towel.

You can also use a marine grade rubbing wax compound and an orbital buffer for this project. Apply small amounts of the compound in sections of your shower and buff it. Make sure you don’t stay in one spot for too long as the fiberglass could burn.

  • Paint for Extra Protection

Painting your fiberglass shower after installation will protect it down the line. It will also save you from spending a lot of time cleaning the enclosure. Once the shower has been set-up, strip off the gloss with sandpaper.

When it’s ready, spray it with a fiberglass primer or varnish. Start at the top and work your way down. Spread the paint evenly to prevent it from dripping. Let it dry for a few hours before applying another coating. Try to apply at least four coatings.

  • Clean it Properly

A lot of homeowners don’t know the proper way of cleaning their fiberglass shower. The surface should be cleaned regularly with a liquid soap or cleaning agent.

  • Take the Necessary Precautions

Aside from regular cleaning, you should also know what to avoid doing. For instance, never use a harsh material on the walls of your fiberglass stall as it could cause scratches.
