BiokleenFiberglass Cleaner M00605 ,Clear

Have used TONS of cleaners on my fiberglass shower surround, with tons of scrubbing to go along with them. This is the first cleanser that "melted" (the only way I can describe it) thick soap scum from the soap rack and walls in less than a minute and immediately wiped clean. Gonna buy more ASAP... It's amazing!!

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 pretty well. Still scrub fiberglass tub floor.

I just ordered two 32 ounces to add to my cleaning supplies.  I originally ordered a 16oz bottle, not knowing how it would work. I have been trying to clean the bottom of my shower for YEARS.  In the past I've cleaned it using bleach.  I would scrub and scrub using a cleaning brush and a toothbrush to clean between the groves.  However, it NEVER looked 100% clean.  Well I ordered this stuff and all I can say is, I wish I would have took before and after pictures.  My shower looks brand new!!  I'm the type of person who read reviews first and the reviews on here that state that this did not clean their shower did something wrong.  I sprayed the shower, allowed it to soak for awhile, then used a sand scrubber.  I did two treatments.  I also used it on the shower glass.  This is a MUST-have in the bathroom.  My shower not only looks clean but it also feels clean.

Used Bio Kleen Fiberglass Cleaner on a white fiberglass shower stall. After two treatments and some scrubbing, results were not as expected. Residual dirt discoloration and soap scum remained. Perhaps a few more treatments will do a better job. However for a product that is touted as a capable boat cleaner I reasonably anticipated much better results for a shower stall with less effort. Will continue to search for a quality fiberglass cleaner.

I used this on my boat to clean up the scum line before washing it. It did do that well but when I went to wash the boat I noticed that there was streaking on the hull where I had also wiped using the same rag. I applied some Bio-Kleen to it with zero results. Went over to the boat store and on their advice tried some paint thinner. Nothing. Tried some acetone. Nothing. Called the company on Monday. Ended up in a conference call with the chemist and a rep from the company and based on the pictures I had sent them they said I had a problem called "streak cleaning" which they had seen before and reassured me that if I reapplied the Bio-Kleen it would come off. It didn't. At this point I had the the chemist's cell phone number and his next suggestion was to use their Bio-Kleen M00805 Polish and Sealant and a high speed buffer. That didn't work either. The fiberglass guy at the Marina took pity on me after watching this for the past 3 weeks and brought me his buffer and some fine rubbing compound and 2 hours later my boat was back to where I had started a month earlier minus my wax job I had paid $250 for in the spring. Although the company seemed very concerned about the problem their product had caused they ignored my letter seeking compensation for the money and time I had spent to fix the problem.

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.

I was skeptical, purchased one bottle to see how well it would work to get soap and water stains out of my two fiberglass tubs and glass shower doors. This has a very mild oder, not to bad and is tolerable.Sprayed it on, let it set a few hours and with littler effort and a scotch brite cleaner and short bristled brush cleaned away the mess with little effort. My wife even commented on how clean everything was.So I have since purchased two more bottles of the cleaner to have on hand.Would definitely recommend.

This stuff works! My shower was dingy over the years and nothing helped so decided to try this. It removed the residue and scum making my shower like-new. I let the product soak in for at least 5 min then scrubbed and repeated a second time. I'm happy with the results as nothing worked.
