Cleaning Fiberglass Showers

I need some help cleaning textured fiberglass shower walls. I cannot get the "grunge" off the floors and soap scum off the walls.

Can't Beat Bar Keepers Friend

Bar Keepers Friend® has an excellent line of cleaning products. BKF has both powder and liquid to clean without scratching the surface. I have used it on marble and fiberglass with excellent results and very little "elbow grease."

Start with Liquid Dish Soap

I've found that the greatest thing to clean shower doors and walls is plain old liquid dishwashing soap with which you hand-wash dishes. It cleans everything extremely well. The first time, you might need to use a soft scrubby sponge. It's also very cost effective and safe to use.

Make the Scum Magically Disappear

I definitely recommend Mr. Clean Magic Eraser! I use it on my tub and other bath fixtures. It doesn't scratch and works awesome!

I have also been able to get crayons and permanent black marker drawings off my white walls among other places. When we first moved into our current apartment, the range had grease all over it that other "tough on grease" products could not remove. The Magic Eraser took it off with very little elbow grease added.

This is an excellent product and I recommend it for the cleaning of anything and everything! Of course, always read the manufacturer's instructions on the box to make sure that it is safe for your intended use. It was also very inexpensive. I bought an 8-pack at our local wholesale club for under $5!

Get Great Results with Vinegar

I never buy store cleaning "stuff" because that stuff is generally just a very expensive way of packaging vinegar, baking soda, ammonia, and or bleach. For cleaning a shower stall and windows, simply spray full strength white vinegar over the wet area. That's it. You need not wipe dry; just walk away. In fact, it is best to let it dry by itself. My shower stall has not had any cleaning done in over five years and you would swear it is brand new!

The Answer is in Your Cabinets

Try regular shampoo like Suave with a scrubby sponge. This works as well as the expensive cleaners without the toxic fumes and is very cheap.

Vinegar mixed with a little bit of shampoo and water in a squirt bottle works good if you need to let it soak to work. The shampoo helps the vinegar to coat evenly and not evaporate so quickly. The vinegar works on the water deposits as well.

Borax is Best

I recently discovered the best way to clean grungy shower stalls is Borax. Not only is it inexpensive, but also there are no toxic fumes or harmful chemicals to eat your hands. Simply pour a small amount onto a wet sponge and wipe away gunk. It also helps to use a scrubber sponge on the floor to really get into the textured areas. It's also great for a number of other cleaning chores. Check out the box for ideas!

Swear by WD-40

I have a friend who swears by WD-40 for cleaning the scum off shower walls. She claims there is very little scrubbing so the fiberglass will not be scratched. Make sure to use with proper ventilation.

Baking Soda and Vinegar - The Dynamic Duo

I just use baking soda and white vinegar. Sprinkle the baking soda all over and then dip your scrub sponge in the vinegar and scrub it. If it's really tough, then I sprinkle the soda and put paper towels soaked in vinegar over the soda and let it sit. There are no fumes and it's very cheap, but best of all, it works better than any of the dozens of products I've bought in the past to remove the "grunge."

Another Liquid Dish Soap Advocate

I've also had this problem. To resolve it, I used inexpensive liquid dish soap and an old plastic bristled brush. The dish liquid cut through the oil, which was holding in the dead skin cells (the grunge look), and also cut through the soap scum. The bristle brush gets into the textured surfaces and took out all the scum and grunge. I rinsed with warm water.

Try Oxi Magic

It's funny that you asked this question, because just yesterday, I finally got our shower clean. I've tried everything to get the grunge off the textured floor, and nothing worked. Then, I found Clorox Oxi Magic. I'm not a shareholder, I swear. I always hesitate using such toxic products and I always think twice before buying them. However, Oxi Magic didn't seem to be so bad. It had no fumes, and it really worked. The hefty price tag was worth it. The shower stall is finally white again! I also like it because it can be used on a ton of different surfaces and fabrics, so it's a good all-around cleaner. As for the soap scum, I use something called CLR. Very occasionally, I use it full strength with a non-abrasive scouring sponge, and the scum comes right off.

Professional Cleaner's Choice

I recommend a product called "Showers-n-Stuff." I found a recommendation for this at another website. It is sold by Don Aslett, who is a professional cleaner. The website is www.cleanreport.com. I used this stuff to clean some tubs and showers that nothing else would clean.

This Really "Works"

Try Works Tub and Tile cleaner. Get the kind you apply with a sponge rather than the spray. It is sold at the Dollar Store. Just wipe it on. There is no scrubbing required. Wait a few minutes, and then using a bucket of clean water, wipe it off. Use the sprayer to rinse. I have used this stuff for years. It "works."

Clean with a Drywall Sponge

I have an old and very grungy looking shower stall that needs to be replaced. Until I can afford that, I am using a tool to clean it that works better than anything else, and I see no damage, which I feared. It's a drywall sponge! You can get them in a variety of courseness types. I got the finest. There are some that are a different degree of courseness/grittiness on three different sides of the sponge. I use my regular cleaners to scrub it and then I let it sit before rinsing off. It works fine on the glass door as well as the tile and the fiberglass flooring in the shower. I found my drywall sponge at a hardware store.
