What to Look for In the Best Fiberglass Shower Cleaner?

Some of the factors to consider when buying a good fiberglass shower cleaner are as follows.

1. The cleaning surface

While using different shower fiberglass, you need to consider the surface you are going to clean. Different shower cleaners have different purposes. There are some options in the market that are labeled as “multi-purpose” cleaners. These are by far the safest bet, and you should buy these or the ones we have recommended above. For instance, if you pick a cleaner for the toilet bowl instead of a shower and accidentally use it, it might bleach the glass and leave discolored stains on it. 

2. The odor of the cleaner

Since you will be spending a significant amount of time in the bathroom, you should make sure that the fiberglass shower cleaner has a pleasant smell. Go in for a cleaner that emits a clean, fresh smell instead of one that smells harsh or clinical.

3. Easy to use options

Most fiberglass shower cleaners already are easy to use. You should remember to buy one which will give you the desired results without you constantly scrubbing it. There are cleaners that will give you a great result by just using it once. Even if you have to keep using it occasionally, make sure they are easy to wipe and scrub.

4. Affordability

Fiberglass cleaners are not something you can just buy once in a couple of years. These cleaners will be a recurring purchase for you as they run out. You should factor in the amount of money you will be spending on them every time. You must pick products that go easy in your pocket. Most of the recommended cleaners in our list are budget-friendly and long-lasting.

5. Environment safe or eco-friendly options

If there is an alternative, one must always consider using environmentally safe or eco-friendly fiberglass shower cleaners. Also, you will be using these near older people or children, so these need to be safe. For this reason, you should avoid using cleaners which have dangerous chemicals in them.

Frequently Asked Questions

How do I get my fiberglass shower white again?

The simplest way to restore the whiteness of your fiberglass shower is to scrub it with a mixture of water and baking soda. Make a paste by mixing these two ingredients, and you are good to go. Alternatively, you can apply distilled vinegar and put it in a spray bottle. You may spray this from time to time and let it soak for a couple of minutes before scrubbing it. Of course, the best and easiest method is to use the fiberglass cleaners mentioned above.

Can I use Bar Keepers Friend on a fiberglass shower?

Yes, Bar Keepers Friend will help you restore that sparkle in the shower or tub soon. Just pour a little of the liquid on a wet sponge and rub the surface well.

Can you use a magic eraser on a fiberglass shower?

Magic erasers are a quick but temporary solution to keeping your fiberglass clean. If you are in a hurry, you may use a magic eraser to wipe off stains or patches of lines, fingerprints, etc. But, sooner or later, you will have to actually spend some time and get the grime off.

How do you clean a badly stained fiberglass shower?

Often fiberglass stains are adamant because of the dirt and grime collected on them over the years. If your fiberglass shower is also like that, you will need to use a deep cleaning option. The cheapest one is to use baking soda paste and water on the surface and wipe it with a towel dipped in vinegar. Let the paste stay for a couple of hours before wiping it off with a clean cloth or microfiber cloth. 

Can you use bleach on a fiberglass shower?

No. Using bleach on any surface is a bad idea. Most people think that using bleach on grimy surfaces makes them clean and white. While that may be true for some surfaces, it is not for fiberglass showers. If you use bleach, the active acidic substances in it will end up discoloring your fiberglass and leaving half-colored patches, which will look worse than stains. Instead of bleach, we recommend using vinegar, which is much safer for you and the fiberglass.

How to clean a fiberglass shower stall?

Your shower stall is probably the dirtiest part of your bathroom because it is inside a place built with the sole purpose of cleaning. All the dirt, grime, bacteria, mold, mildew will collect around the fiberglass, staining it over time. To ensure that this does not happen in the first place, you will need to give your shower stall a deep cleaning once every month. This will make sure that no deposits build up around the area. You can use a clean microfiber cloth or a clean cloth to wipe down the stall properly. You can also follow up with vinegar or baking soda paste if you want to go the extra mile.

To ensure that your fiberglass shower stall stays as clean as possible, avoid leaving every surface watery, switch on the ventilation to remove the moisture and use a good cleaner from any recommendations above to do a thorough job.

How to clean a fiberglass bathtub?

Fiberglass bathtubs are aesthetically pleasing to look at but equally hard to keep clean. They are also less strong compared to other tubs and can easily be scratched and stay unclean. The best thing to use to clean fiberglass bathtubs is to use a liquid agent, such as a special bathtub cleaner, liquid dishwashing soap, or even detergent. To properly clean up, use a reliable fiberglass cleaner from the ones suggested above.

How to clean a fiberglass shower pan?

Shower pans are at risk of being dirty most of the time as the grime and dirt seep into it the most when we are in the shower. Like your stall, they need regular cleaning, at least once a month. You can apply the baking soda and water paste to the edges and on your shower pan and let it stay for some hours. 

Another option is to use a particular bathroom cleaner to eliminate any tough stains or discoloration on the pan. Magic Erasers are also a sure way to help you get rid of the dirt accumulated on the fiberglass. 

Does WD 40 Clean Fiberglass Showers?

Yes, WD 40 is an all-purpose cleaner that works on almost everything. It is made so that it will get rid of ugly stains or difficult spots easily and instantly. It will also get rid of any hard water stains, soap marks, and grime pretty well.

Wrapping Up

Just like every household item, even fiberglass showers need maintenance from time to time. No product will help you restore the shine of your fiberglass shower forever. It is a matter of regular upkeep. To ensure that your fiberglass shower stays intact, clean, and usable for a long time, we recommend that you use the products suggested above to get the best results.

We hope that this guide helped tell you ways of cleaning your fiberglass shower and that you will follow the proper steps to ensure your shower’s longevity.
