Fiberglass shower

Personally, I like fiberglass showers and tubs over regular acrylic or glass. They have that nice shine that cannot be paralleled by anything else. When you enter a bathroom and see a fiberglass shower, you think that is fancy. It leaves a lovely impression all over and it’s relatively easy to fix a fiberglass shower. I think that fiberglass is a lot more elegant than glass or ceramic, but then again, that’s just me. Additionally, it’s quite easy to fix a fiberglass shower or tub if you follow the How To Repair a Fiberglass Bathtub – Fix Cracks and Holes guide.

If you are planning on getting a fiberglass shower, keep in mind that cleaning it may prove to be a nightmare at times. With the wrong cleaning product, that is. Soap scum and grime don’t care just how fancy your shower is. They will deposit anyway. And I don’t know if you have ever seen a clear fiberglass shower door covered in scum. It looks terrible. And the worst part is that the more you let it sit, the more you are going to scrub to get all that filth off. That is why you need a fiberglass shower cleaner solution designed to easily clean that dirt.

Fiberglass cleaner vs conventional cleaning products

As you are well aware, there is a cleaning product for virtually anything. One cleans the windows, another the dishes, the spots on the floor come off with a different cleaning solution, and so on. It’s only natural that fiberglass should have its own cleaning solution, one that is meant to do the job the best way possible. With that comes certain advantages.

Easy cleaning

You don’t have to struggle every time you need that shower cleaned. Regular cleaning solutions will do the job, but not properly. Chances are you can do more damage than good. You can scrub and scrub, but the result will not show themselves. I am not saying that it will not help, but the trails that a regular cleaning solution leaves on fiberglass shower doors are appalling. And no matter what you do, you’ll just keep leaving trails. Whereas a fiberglass cleaner will not have that consequence. They are specially designed not to leave trails. The shower doors will look as good as new.

Less time cleaning

The amount of time you spend cleaning the fiberglass shower is a lot lower than cleaning it with a regular formula. Because the fiberglass cleaner is specially made for that, the cleaning itself will take just a few minutes. All you have to do is pour the solution on the affected area or on a piece of cloth, and simply wipe it all off. It has an immediate effect, and usually, you don’t have to let it sit. There is no scrubbing involved either. 

Better than homemade cleaning solutions

You don’t have to bother concocting all sorts of homemade fiberglass cleaners. I noticed that there is a practice among people of making their own fiberglass cleaner from different substances like vinegar, baking soda, or even bleach. There is nothing wrong with it, I think, I hear they do a pretty good job. But isn’t it more convenient to use a cleaner straight from the bottle? I believe that it is. On the plus side, it’s better to use something that professionals made for a particular purpose, rather than you doing it.

What to look for in the best fiberglass shower cleaner?

Fiberglass is a highly resilient material, you cannot damage its composition easily. However, that doesn’t mean that it can survive any chemical reaction. Especially when you think about shower doors, for example, they are transparent. Any dent, any scratch, or burn will be noticeable. I even saw some disasters involving some kind of white spots that turned the see-through fiberglass into an opaque white. I don’t know how that lady managed to accomplish that. Who knows what she used? But the point is that it will never happen with a fiberglass cleaner. That thing has been tested over and over again, so you know that your shower will survive it. So here is what you want from a fiberglass cleaner.


It has to be nonabrasive – that is one of the most important aspects. If you use an abrasive cleaner, in time you will notice small scratches all over the shower. You may not see it after just two or three cleaning sessions, but as I said, in time, the consequences will emerge. Fiberglass is known for its sturdiness and durability, but it can still be affected by tiny scratches. Just give it some time, and you will see. But if you use a fiberglass cleaner, that will never happen. It’s specially designed to leave a glossy trail behind, not microscopic scratches.

Effortless cleaning

It has to contain a powerful formula – if you wanted to scrub for a while, you would have gone for a regular cleaning solution. Fortunately, fiberglass cleaners are known for their immediate effect. The ease of use it’s one of its benefits. You don’t have to let it sit. Just apply and wipe. You are done in a couple of minutes. The strong but gentle formula will remove everything from soap scum to grime in a matter of minutes. No scrubbing is required whatsoever. You only need a cloth.

Glossy finish

It should leave a glossy finish behind – that is one of the unique features that regular cleaning formulas don’t have, unlike a fiberglass cleaner. That is one of the things that make a difference. And you don’t necessarily have to wipe the area dry in order to get that glossy finish. It’s enough to rinse with water. However, if you want that gloss to last, it is recommended to wipe the area dry with paper towels or with a cloth made of microfiber. Just so you know, the glossy finish not only makes the shower look shiny but also proved protection when you use the shower next time.

Smell nice

It should smell nice – vinegar, bleach, and baking soda don’t have a really sweet and fresh scent. Personally, I hate the smell of vinegar. I know it goes away eventually, but I would still rather enter the bathroom and feel as if I walked into a soap factory than stand the smell of vinegar or other nasty-smelling chemicals.

What are the best fiberglass shower cleaners?

This is not a matter of taste. A fiberglass cleaner either works or doesn’t. One of the best ways to find that out is through reviews. Not everyone leaves one when they are satisfied with the product they bought, but almost all people leave a bad review when they are discontent. Just follow that logic, and you will see that you will eventually find the best fiberglass shower cleaner. Here are a few suggestions.

Weiman Fiberglass Cleaner for Bathrooms

Weiman Fiberglass Cleaner for Bathrooms

With Weiman Fiberglass Cleaner you will make that shower look as good as new in no time. It removes grime, filmy residue, hard water spots, and soap scum without effort. You don’t have to scrub either. Just apply the liquid to the affected areas and wipe it off with a cloth. After that, you just have to rinse, and you are done. For a glossy finish, it’s recommended that you wipe the shower with a microfiber cloth. That will prevent other spots from forming, especially if you live in an area where there’s hard water.

The cleaner from Weiman is multi-purpose. It’s not limited to showers. You can also clean bathtubs, spas, pools, vanities, sinks, tile, and even boats, and RVs. As long as something is made of fiberglass, you can clean it effortlessly. You will notice that this cleaner also restores the natural color and texture of the surface you clean. It will leave a shiny trail that will satisfy you greatly.

The formula is nonabrasive, so you don’t have to worry that it will scratch the shower doors. It’s gentle with any other surface you may want to clean. Keep in mind, though, that this formula is not recommended on painted or varnished surfaces. Also, don’t use it on aluminum or magnesium wheel rims. The reason I am telling you this is that some people use a similar formula for anything other than fiberglass, which may lead to damage.

From what I can see people are very satisfied with the product. Weiman Fiberglass Cleaner is very efficient, and the results are amazing. I am sure that you will be satisfied as well.
