Biokleen Fiberglass Cleaner M00605 ,Clear

This stuff makes fiberglass shower a breeze! It also removed stains that wouldn't come out with my regular cleaning. Very easy to use - just spray it on, rub down the surface with a rag, and wash off. As a bonus it smells really good (wintergreen). I will be buying this again!

We have lived in our house for just over 7 years and I have never been able to keep our textured fiberglass shower floor clean. No matter the product - Magic Erasers, Scrubbing Bubbles, bleach products - nothing would cut through the gray grime and gunk and make the floor white. Bio-Kleenex has done the trick! I have never seen our shower floor this clean. It looks new. I generously applied the Bio-Kleen and let it sit for over 30 minutes. I scrubbed it with a nylon bristle brush and rinsed with hot water. I repeated this step once more and then did a quick spot scrub a third time. It has a strong mint-like smell, but I would not call it offensive. I was fine with the bathroom fan on. I wouldn't let my kids hang out in there, but I didn't feel like I was going to pass out. Overall, this is a total win! It is the answer to my icky-floor problem and has saved me tons of time and frustration.

Every time I have bought this product it has been in a 32oz size this one came as 16oz supply and cost more than the 32oz that I paid before. Sizes were not clearly posted you have to dig deep and then it was displayed in ml. The product works amazing on PVC deck railing removed 8 yrs of oxidation ,

It took 4 good sprays before I was really satisfied and it still was not back to the original color as I had hoped. I'm in an apartment and I like my place looking clean and I hate the fiberglass tubs and showers. But so far its the best as far as - easiest and cheapest I have seen to get it this clean.

I'd tried so many products and nothing would get the gunk off of the fiberglass shower in our house that had been a rental for a decade. We were discussing replacing or some sort of refinishing of the shower. I read reviews for this product and told my husband I'd see if this last effort worked before getting estimates. I'd read about the fumes so I put on a full respirator mask. Overkill? The scent is a mix of chemicals and wintergreen. It's not bad but I don't think it should be inhaled. Anyone that uses heavy chemicals should have a respirator mask period. Anyway, I sprayed a small area, waited 5 minutes and used a Magic Eraser and with very little effort, the gunk just melted away! I sprayed a larger area and did the same with the same results. My husband looked and said how much better the shower looked but that he could see where I sprayed snd scrubbed, there was more gunk above it. So today I sprayed that upper area and went at it and it's still wet but I can see the gunk is gone. Unfortunately there's more to do but I'm confident the rest will come off. I've ordered 2 more bottles! This stuff works!

Works Ok, but not fully as advertised. With a good brush and lots of "elbow grease" the scum is removed but you can still see the stain left behind, though much diminished. Protective glasses, clothing and rubber gloves should be used as the product is somewhat caustic.

Very happy I found this product which is the only safe and effective way I’ve found after 40 years to remove hard water scale on my bath/shower.

I used it on my 30 year old washroom sink. Very very strong smell but who cares as long as it works right? Well, it took the entire bottle over many attempts at spraying scrubbing letting it sit. It still didn’t work as all of the reviews said it would. Very disappointed, but does look better but you have to work at it. There’s got to be something better out there, I’ve tried many different products.
