You will find different kinds of materials used to make bathtubs and showers. However, they look shiny. Materials like ceramic tile, porcelain, stone slab, enamel, acrylic, or fiberglass are usually used to make these things. Some of the materials don’t even look different after finishing. So, you need to observe closely. You should know well what these materials look like.

Usually acrylic looks as if you have stretched out a plastic. Plain fiberglass looks glass-like whereas acrylic seems plasticky. However, natural stone, on the other hand, doesn’t seem to be shining even after polishing.

Unlike fiberglass, porcelain is usually a little heavier and chunkier because of its base of cast iron. By observing the shower, identify if it is fiberglass or not. No matter which material is used, you should not use harsh chemicals to clean.

But it’s never a good idea to follow. Remember, you are washing a fiberglass shower. And fiberglass is used in cars, bulletproof vests, and swimming pools. Just think for a while. Would you allow any abrasive items near your car? So, avoid these kinds of rough things to cleaning your shower.

Ammonia Instead of Bleach

When you are wondering how to clean a fiberglass shower, some people may tell you to use bleach. Bleach is not good for your lungs and skin. Moreover, it can redden your eyes and you can feel itchy on your skin. Similarly, it is harmful to the resin in fiberglass.

However, you can use ammonia to get rid of the watermarks. Be careful while using ammonia. Too much of it into the lungs can be as harmful as breathing bleach. Before using ammonia, dilute it into the water and keep the room well-ventilated.

Avoid Combining Commercial Products

Many people mix this and that to make something new. They combine essential oils, cornstarch, and sometimes fermented fruit rinds. Some people mix some commercial products.

They think every other thing will work to clean the fiberglass shower. But in reality, this is not the case.

You should always remember that these all are chemicals. When mixed, they can react badly. It might cause a big accident. So, do not mix different objects while cleaning the fiberglass shower.

Rather, you can go for making homemade cleaner by mixing a mild acid with a mild alkali. As a result of their mutual reaction, there will be fizzy foam. Use it immediately after making it.

Plain Vinegar Works Well

The oil-based dirt that we see in most showers is easy to clean with mild acid. For instance, vinegar is a wise choice in this regard. Pour some vinegar into warm water and keep it in a spray bottle.

Now sprinkle the water-vinegar mix over the shower walls. Keep it like this for at least ten minutes. Now run the shower and see how it moistens the mess and wipe off the gunk.

If you are using a rain showerhead or a regular showerhead, you can do it more conveniently. Just keep the water on a bag and tie the bag to the showerhead. The next morning, you will do everything clean and shiny.

Dishwashing Liquid Mixed with Vinegar

If plain vinegar doesn’t work well, then you have another process to use it. Mix it with your dishwashing liquid. Well, the white vinegar can be replaced with some mild household acids. For example, you can use hydrogen peroxide or apple cider vinegar.

Along with that, dishwashing soap will add foam. Spray this mixture on the shower wall. The longer you will leave it there, the better it will clean.

Foam works well on stains. When foam sits on the stains, it makes the stain soft. Besides that, if there are any grimy particles on the surface, they also get softened. So, it becomes easy to just wipe off the dirt from the surface.

Another trusted combination is baking soda with dishwashing liquid. As a result, you will get an abrasive mixture. Now you can easily rub off oily stains from the shower without harming your fiberglass surface.

Using Truck Degreaser

We already know that fiberglass showers use the same material that is used in most modern cars. And the washroom stains are mostly from oily substances. So, it’s easy to understand that the truck degreaser will work tremendously well here.

It will soak the grimy scum and let it wipe off without much effort. Therefore, you will see your bathroom walls clean and shiny in a minute.

To remove the stubborn stains, let it sit for a while. To get the best result, use a sprayer and sprinkle the liquid directly on the shower walls.

Rinse The Wall

After that, use cold water to rinse again. That will remove the soap foam, or scum as well. Now clean the watermarks. Use a soft rag to wipe the wall.
