Cleaning and Preventative Maintenance Fiberglass Do’s and Don’ts

Fiberglass showers and basins may be used in a variety of ways. However, there are a few things you can do to avoid soap scum and corrosion from accumulating. A few cleaners should also be avoided. To learn more, go through this list.

Clean off the shower with your cloth after showering or bathing. This may help prevent corrosion and detergent scum build-up, which is particularly important for those who have hard water.

When cleaning with solvents, always use the correct safety equipment, such as gloves and old clothing. When using steel wool or harsh cleansers, take care not to damage the fiberglass. If you have colored fiberglass, resist using hydrogen peroxide since it can discolor it. Make careful to thoroughly rinse the chemicals.

Fiberglass Shower Refinishing

With Ease, Remove Tough Stains from Fiberglass Tubs

Fiberglass showers are long-lasting. This makes cleaning them a breeze. However, it’s critical to follow the dos and don’ts of washing fiberglass to avoid creating more work for yourself in the long term.

Tips to clean fiberglass shower:

Tips to clean fiberglass showers are listed below:

  • Determine The Source Of The Stain
  • Wipe It While It’s Still Warm
  • Make a paste of vinegar and dishwashing liquid:
  • Make a paste of vinegar and Baking Soda:
  • Use a Degreaser 
  • Rinse with both warm and cold water

I will now elaborate on the guidance given above.

Determine The Source Of The Stain

Fiberglass, unlike other typical shower and tub surfaces, has a glass basis, thus the name. Fiberglass is made from melted sand that has been treated with great heat before being blended with resin. Algae, dissolved salts, corrosion, and spots from acidic cosmetic products may all be found in showers.

Another bathroom concern is soap buildup. As soap has an oily foundation, it develops in little pools and splashes and maybe rather obstinate when it collects. Typical soap is manufactured by using high-pressure heat to handle fats and oils, then filtering, distilling, and adding alkali.

Make-up, hair products, spilled medication, bath salts, detergent, toilet sprays, and children may all discolor your fiberglass showers. Kids in their own category since they might bring anything into the restroom, from crayons to cookie crumbs.

Wipe It While It’s Still Warm

The dirty remnant of sebum, cleaning agents, and biological dust causes many shower spots. That’s why cleaning the bathroom is simpler when it’s steamy. Because the water and heat vapor break fatty filth, it washes away easily. After a shower, though, not everyone washes their walls.

Another option is to operate the shower for 2 to 5 minutes at its highest setting. This nicely steams the shower, requiring little elbow grease. You may also heat your washing solvent for a minute or two in the oven. However, if it’s a foamy cleanser, be cautious!

Make a paste of vinegar and dishwashing liquid:

Add a small amount of any light dishwashing chemical, if simple vinegar isn’t working. Any moderate domestic acid, such as cider vinegar or hydrogen peroxide, may be used in lieu of white vinegar. The washing soap thickens your soap’s froth.

Foam is beneficial because the flutes in it remove stains and bring dirty grime to the top, where they can be simply wiped away. If you’ve run out of domestic acid, try spraying a mixture of warm water and a few droplets of dish detergent. It cleans better the longer it sits.

When you don’t have vinegar on board, combine your dishwashing solution with a tablespoon or two of sodium bicarbonate as a substitute. It makes the solution somewhat gritty, allowing you to scrape away grime without harming your fiberglass areas. Circular movements should be used while rubbing.

Make a paste of vinegar and Baking Soda:

Scrubbing your fiberglass walls or scraping the shower door might produce scars on the surface. Instead, combine vinegar and bicarbonate of soda to make a gritty paste. Your paste will be more powerful if it is thicker. However, mixing huge amounts is impractical.

As a result, prepare a quarter cup or half cup of paste, apply it immediately to the spot, and let it dry for as long as necessary. This might last anything from 30 mins to an entire day. If necessary, massage it in. Wash it off with clean water or wipe it off with a moist towel after it’s set.

Use a Degreaser 

Fiberglass showers are built of the same material as many current vehicles, and bath spots have a greasy undertone, as we previously said. So it seems logical that a solution designed to remove oil from vehicles would also work on a fiberglass toilet. 

It appears to work instantaneously, soaking up dirty muck and allowing it to be easily wiped away. Your bathroom walls will be pristine in minutes, however, if the stains are very tenacious, you may let it soak for a little longer. Use a sprayer directly on steamed-up shower walls for the greatest results.

Rinse with both warm and cold water

Operate the shower once more to create up clean steam after your selected cleaning substance has attained the intended result. Then, using a portable showerhead, a hose, or a spritzer bottle loaded with clean water, soak the walls. Any greasy remnant will be removed with a warm rinse.

Steps of rinsing:

  • To remove all of the detergents, rinse with cold water. 
  • Clean the walls with a dry, smooth, lint-free fabric to avoid watermarks. Microfiber is the greatest option. 
  • Finally, turn on your toilet fan or open a window to allow any wet air to escape, avoiding damp and mildew from forming.
