Bio-Kleen M00607 Fiberglass Cleaner, 32 oz.

We recently purchased a new home and the master shower pan needed a little help. I tried standard cleaning solutions to no avail. I then used the baking soda/white vinegar combo with a Mr. Clean magic eraser which did remove a lot of it. However, it was still a little cruddy to where I still did not feel comfortable using that shower. In comes Bio-Kleen. I sprayed the stubborn areas and waited a few minutes. I then used my magic eraser to scrub. I could not believe my eyes. When I tell you my shower is almost new looking, I am so pleased. This stuff really does work with a little time and arm strength.

The reviews were encouraging so I thought I'd give it try. What used to take hours and whole box of magic erasers was done in 15 minutes with little to no effort. Pan looks brand new! If you have fiberglass that needs cleaned this is your product. Make sure you turn on the exhaust fan and leave the bathroom for 10 minutes. Its a strong odor but worth it!

We closed on our new home in 2006. One of the first things I did was install an attic fan then a whole house water water and water softener. Over the year we had little staining which we wanted to remove. We tried the Bio-clean which actually lightened the staining. So far, we did two applications with the staining almost gone. As I stated, it’s not a magic nor snake oil but it does improve the stains.

I was disillusioned when I opened the box and found the bottle sprayer was cracked, broken, and taped together. I had lowered expectations when I applied the solution to my fiberglass shower. The gases it produces requires a mask for application and the result is not readily apparent but, it works fantastically. You do have to apply the old addage, "All good things come to those who wait." I checked the shower a couple of hours later and where I had applied the spray was clean and shiny....almost like the new shower it was 45 years ago! I am very happy with my purchase. Thanks, Amazon, for pointing me in the right direction!

I had to take the time to write a review of Bio Kleen fiberglass cleaner. I tried a few methods I found on UTube but did not get any results. This product saved me so much time. The directions are clear, spray on let stand for atleast 10 minutes! Unbelievable!! The brown stains on the hull of my boat just washed away. No scrubbing required. My boat is used primarily in brackish waters of the navasink river in NJ. The hull was extremely stained at end of season. Never dreamed it would look like new again. It also removed small rust stains around chrome trim. No odor washes away without staining.

It did a pretty good job of cleaning my fiberglass walls in my guest bathroom. Didn't take everything off but still worked better than other products i I have purchased to this task. I'll probably buy it again.

Did not clean my fiberglass tubs and showers any better than any other cleaner.

This Bio Kleen M00607 fiberglass cleaner is more than awesome!! After cleaning my shower, my husband came in to look at it and he said it looks like our shower was replaced with a brand new one. I should have taken before and after pictures. This product is MORE than a 5 ********** I've already told several friends and family about this product. I will definitely buy this product again. I would love to find it in either 1/2 or 1 gallon jugs.

Excellent product. Used it to remove yellow stain on my white hull. Did a great job. I bought it again this year.
