7 Best Fiberglass Shower Cleaner in (2022) – Reviews and Buying Guide

Fiberglass showers look sleek and elegant but only if they are totally transparent and free of stains. Unfortunately, as time goes by, the glass becomes dirty due to consistent exposure to hard water, soap scum, mildew, mould, detergents, dust, and many other things.

Thus, to retain the original transparency of a fiberglass shower, you need to clean them daily, without missing even a single day – a thing that seems nearly impossible. If you tend to clean the glass after a week or two, odds are the stains become stubborn, sometimes permanent, which means you need to make more effort or hire a professional to help wipe them away.

These stains don’t only shoddy the glass to make your bathroom look messier but over such an unhygienic surface, bacteria may start to grow which, in turn, will put your and your family members’ health at risk. To wipe out the mineral deposits from the glass surface, you can’t employ a scouring rag since it can leave scratches over it.

Thankfully, the market is full of such efficient and mighty fiberglass shower cleaners that can clean out even the toughest and long-term stains in a single-use. The only problem is that not all the fiberglass cleaners work as fast as you want. Also, some fiberglass cleaners only work in hard water or soft water.

1. Bring It On Shower Door Cleaner

Most of the bathroom cleaners available in the market are those which are loaded with heavy chemicals and acids. Those cleaners, if used without proper attention, can burn your skin horribly and may also contaminate your home’s inner atmosphere. That’s the very reason why we put this product at the topmost ranking!

This shower cleaner doesn’t contain any sort of additive, chlorine bleach, and chemicals which makes it perfect to be used by anyone – of any age, without the need of adult supervision. You can use this oxygen bleach, non-toxic cleaner to clean not only your fiberglass but also to wipe off the stubborn mould stains from the bathtub and tile grout.

Since these days, water supplied by the main pipelines is hard which means you can’t expect the mild cleaners to work properly. But thanks to the manufacturer who made this cleaner potent enough to work even in hard water. Not only this but I was surprised to see that this cleaner can clean the toughest rust stains, along with mineral deposits, in just ten minutes.

  • Clean stubborn stains in ten seconds
  • Non-toxic, oxygen bleach
  • Equally effective in hard water
  • Completely safe around kids and pets
  • Do not smell nasty
  • Reasonably priced
  • Ensures effortless cleaning
  • It needs elbow grease to show magic

The thing which impressed me the most about this fiberglass cleaner is that it doesn’t smell nasty. Instead, as soon as you open the bottle and spread it over the glass surface, your bathroom begins to smell like fresh mint. Also, since the formula does not contain toxic bleaching agents like sodium hypochlorite and sodium hydroxide, you can use it even without wearing gloves.

All in all, with this, bring it on shower cleaner, you can scrub away the mineral deposits, hard water stains, and rust, without doing any effort. However, these stains will likely reappear after a couple of weeks which means you need to clean your shower glass regularly to keep things under control.

2. Bio-Kleen M00607 fiberglass Cleaner

This fiberglass cleaner is also one of the best-performing glass cleaners on the market and the main reason why it’s my favourite is that it shows its magic in seconds. Most fiberglass cleaners need ten to fifteen minutes of application after which you need to scrub the surface thoroughly and rinse it to get the clean glass.

Whereas with this bio-Kleen fiberglass cleaner, you can get rid of the toughest mineral deposits, mold, and rust stains with literally zero effort. The formula exists in a gel-like viscosity and comes in a spray bottle. As soon as you spray the solution over the glass surface, it penetrates the buildup, breaking it down so you could wipe it off easily.

Since a rapid action technology has been added to the liquid, the whole process, penetration to build-up and dissolving it, takes only a fraction of seconds. I was in complete awe when I got a brand new and sparkling shiny fiberglass in fifteen minutes. To check the effectiveness of this product further, I applied it over multiple surfaces including metal, RVs, fiberglass boats, props, rims, tires, tiles, grout, outboards, and many others and it never failed itself even once.

  • Penetrate and dissolves the stain in seconds
  • Shows results instantly
  • Easy application
  • Free of toxins and harsh chemicals
  • Don’t need elbow grease
  • Comes within a spray bottle
  • Reasonably priced
  • Can be used on multiple kinds of materials
  • Fumes are quite strong

Since this cleaner is non-abrasive, I’d like to recommend this product strongly to the boaters. Most importantly, you don’t even have to scrub the surface to get the job done. Just spray, wait, and wipe! The most impressive feature of this product is that it’s safe for the environment, even despite being highly potent.

The formula doesn’t contain toxic bleaching chemicals, aerosols, or any other toxic or skin-burning chemical which make it safe not only for you and your pets but also for marine life. The only problem is that the fumes originating from the formula are quite strong but you can wash them away using plain water.

3. Weiman Tub Tile and Fiberglass Cleaner

Wiping off the scums, grimes, and calcium deposits from the glass and other materials could be quite painful and even if you use a high-end glass cleaner, odds are it leaves the absurd-looking stains behind or they reappear in a few days.

However, I found this product something different in this respect. Due to being a heavy-duty and potent formula, it is capable of removing the toughest limestone, rust, hard water, and soap stains even without demanding you for rubbing.

That’s why the experts highly recommend this product for boat cleaning as scrubbing off an entire boat could be back-breaking. Since this cleaner doesn’t demand any additional effort, It’s an ideal choice for such heavy-duty cleanup jobs. Besides this, I found this product quote suitable to be used in toilets and bathrooms as it doesn’t give off stinky smells.

I have used it on different surfaces in my bathroom like in bathtubs, tiles, ceramic, porcelain, shower stalls, RVs, and grouts, and it was equally effective in all of them. The only problem I found while using this fiberglass cleaner is that it is not very effective to deal with discoloration stains.

Sadly, the formula contains 2-butoxyethanol which can hurt both your eyes and skin so you have to use it only after wearing protective gear. This chemical could also disrupt the quality of aluminium, painted surfaces, magnesium wheels, or alloy so you better not use it to clean them.

  • Non-abrasive yet powerful cleaner
  • Can be used on multiple kinds of surfaces
  • Easy to use
  • Cleans toughest stains in seconds
  • Doesn’t tarnish the quality and shine of the glass
  • Ideal to clean shower glass and boats
  • Perfect for heavy-duty and more serious cleanup chores
  • May hurt eyes and skin
  • Not suitable towards aluminium and alloy
  • Slightly costly

However, using this solution is quite painless since all you have to do is apply the formula directly from the bottle to the dry surface via a non-abrasive brush. Wait for a few seconds until the cleaner would get absorbed into the surface and then, rinse it out using plain water and get your clean and shiny fiberglass in a second.

In a nutshell, I found this cleaner to be perfect to clean fiberglass with tough stains that can’t be removed by common cleaners. Its non-abrasive yet heavy-duty formula can wipe off grimes, hard water stains, rust, scums, limescale, and many other spots without demanding any elbow grease.

4. Rejuvenate Scrub Free Soap Scum Remover

My ultimate favourite fiberglass cleaners are those which contain a bleach-free formula and are free of alarmingly dangerous chemicals since such products not only deteriorate your health and environment but also cause glass discolouration. If you are looking for a glass cleaner that is free of all the harmful agents and harsh chemicals, get this Rejuvenate scrub-free glass cleaner.

Despite having an eco-friendly composition, the formula is highly effective and can clean all sorts of stains in a few seconds. Not only is this product safe for humans, pets, and the environment but it also comes with such wonderful agents that restore the original elegance and shine of your fiberglass. As the name of the product shows – REJUVENATE.

Due to being free of skin burning, and harsh chemicals, you can apply it even on delicate surfaces for cleaning purposes including plastic, porcelain, ceramic, chrome, and natural stones. Thankfully, the product comes in a spray bottle which makes the whole process much easier. Just shake the bottle before application and press the nozzle all over the surface.

  • Versatile
  • Can be applied to different materials
  • Removes soap scum in three minutes
  • Easy to apply
  • Doesn’t need any elbow grease at all
  • No harsh chemicals
  • Eco-friendly composition
  • Free of fragrance
  • Tough stains might require a little scrubbing

Yes, it’s scrub free which means no efforts are required to get your shiny glass doors back. I also tested this product on an old bathtub at my grandma’s home and let me tell you, that tub was extremely dull by the 20 years worth of soap scum buildup. I let this formula stay in the tub for five minutes and prepared my nerves to scrub the whole tub but as I approached to wipe the formula off, I was in awe.

You don’t even have to wipe the formula off as I just rinsed it with clean water and saw the tub, for the first time, that much shiny and clean. The formula doesn’t smell too strong, it’s free of fragrance, so using it is also painless.

5. Scrubbing Bubbles Mega Shower Foamer

This shower cleaner is also quite effective for removing the stubborn stains of not only hard water and soap scum but also towards cleaning dirt, lime, calcium, grime, and other mineral build-ups. You can use it conveniently over almost all the bathroom interior including shower stalls, vinyl curtains, tubs, and doors.

The best thing about this product is that It not only removes the nasty stains from the surface but also impart a sparkling shine which makes the glass look new. Most importantly, the cleaner does all these things without making you wait for long painful minutes. Just apply the formula and you’ll be able to get the result instantly.

The formula comes in a spray bottle, having a fine nozzle attached to the head. Since its consistency is foam or gel-like, you better shake the bottle well before applying it and also keep shaking it on and off during the operation. To prevent leakages or spilling, the nozzle comes with a lock feature using which you can set it at either ON or OFF position.

While trying for the first time, the formula hits the glass door and collides back to me in the form of splashes. To prevent this from happening with you, I’ll advise you to maintain a distance of about 6-8 inches between the bottle and glass surface, while pressing the nozzle.

  • Works instantly
  • Remove all types of stubborn stains
  • Easy to apply
  • Doesn’t require scrubbing
  • Comes in a spray bottle
  • The nozzle can be turned ON and OFF
  • Effective to clean glass, vinyl, tubs, and tiles
  • Long-lasting
  • Little product in the canister
  • Overpriced

Apply the formula thoroughly all over the surface and wait until the form formation begins. After a few minutes, wipe off the foam using a rag and that’s it.

So, as you see, the product doesn’t need to be scrubbed nor does it require hefty elbow grease to show its wonder. The only problem is that the formula you’ll get in the can is very little so if you are up to extensive cleanup, you’ll need to buy several bottles.

6. RMR-86 Instant Mould and Mildew Stain Remover Spray

For all those dealing with so many black spots in their bathrooms, floors, and roofs, this product is a life savior. In one of my unused bathrooms, I had a huge spot covered with black mould over which I tried tens of cleaning products but not even a single one came out to be effective – not even the commercially available bleach.

Then I used this product and it got my heart. The formula is, although, not eco-friendly at all as it contains chlorine bleaching agents and sodium hypochlorite is a very concentrated form, but that’s the main reason why it’s super effective. To use it safely, I advised you to wear an entire PPE along with face and eye protection. Remember that if even a slight amount of formula comes into contact with your skin or eyes, the results could be extremely severe.

On applying this formula to bathroom tubs, toilets, and shower stalls, I was a little scared to see how my bathroom got filled up with chlorine and ammonia gas. Thankfully, my bathroom was well ventilated so I didn’t get prone to chemical toxicity. Unlike other shower cleaners, you can’t just wipe it off instead, you have to let the formula dry and then rinse it off with hot water thoroughly.

  • Extremely powerful cleaner
  • Can remove mould and mildew in seconds
  • Works on the toughest stains
  • Clean and disinfect the stalls simultaneously
  • Long-lasting
  • Can be used to clean stalls, doors, floors, and roofs
  • Not safe for skin and eyes
  • Overpowering odour

If you follow all the safety measures, the product is fabulous – the most powerful shower cleaner that can restore even the dullest stall to its original glory. Also, the odour of this product is overpowering which means you have to leave your territory with this formula for some hours to get the job done.

7. Earth Friendly Products Shower Cleaner Spray

The last shower cleaner is unique in its composition as unlike previous products, it doesn’t contain lab-made toxins. Instead, the formula contains tea tree oil which is not only highly powerful to clean scum and mineral deposits but also soothing towards the glass surface.

I was thinking of this product as one that takes hours to show results but I was wrong. The cleaner can clean soap scum, hard water spots, dirt, deposits, smudges, and even mildew in seconds and the effectiveness is also the same for almost all types of surfaces including tubs, tiles, shower walls, and curtains.

Other ingredients of this formula are also plant-based like aloe vera, essential oils, and tea tree oil which gives off a very fresh and pleasant odour. It’s also scrub-free so getting this shower cleaner for everyday use would be the best decision you’d ever made.

Buying Guide

Keeping your fiberglass shower clean is essential for maintaining quality health and hygiene and that’s why purchasing the best fiberglass shower cleaner should be one of the most important parts of your to-do list. To ensure that you are buying only the best product, here are the points you need to consider


Mostly the shower cleaners that are rich in chemicals or loaded with bleach possess overpowering fragrances – the unbearable one. Such fragrances could not only irritate you and your kids but even your pets may find it annoying. Thus, always go with a cleaner having no or mild aroma.

If you want a cleaner mainly to clean your shower stalls, go with the glass cleaner specifically. On the other hand, if you want an all-in-one cleaner to remove stains from all the parts of your bathroom, get a hybrid cleaner. Don’t forget that you can’t use a tile-cleaning formula to remove stains from fiberglass since it can cause discolouration. Thus, always go through the product description and look whether it’s perfect for your needs or not!


Always prefer to get a shower cleaner having the least number of harsh chemicals. If you can find an all-green cleaning formula, that will be fabulous. But if you can’t find a natural cleaner, go with the one having mild chemicals so it won’t contaminate your home environment nor would it harm marine life.

Elbow Grease

Most of the shower cleaners need scrubbing to wipe off the stubborn stains completely. However, some cleaners can dissolve the grimes and stains without scrubbing. You just have to apply them over the surface, wait for a few minutes, and wipe them off. So, always buy the shower cleaners that require the least elbow grease.
