    M006 cleaner

    Cleaned the discoloration below the water line pretty well after leaving for 10 min. Not as good as the acid cleaner but does not damage the galvanized trailer. Yet to determine how it will work on marine growth.

    This product is amazing to say the least!!!! Hands down better than anything I've used in the past. Great price and friendly customer service. Deserves 10 stars!

    Bio-Kleen Fiberglass Cleaner -- More Than Boats

    I've used this product for several years, and I continue to be extremely pleased with the results. Not only does it work well on the boat, but it does extremely well cleaning fiberglass showers.


    aluminum/fiberglass cleaner

    this is a great product and works as stated. you need to let it stand on for about 5 minutes and then rinse. this is the fiberglass cleaner and it works on ALUMINUM. the aluminum cleaner , which I have purchased also works great but doesn't foam as much and runs off quickly. both are great !! a little pricey but its up to you how often you use it. give me a deal and ill buy more .

    Cleaning fiberglass boat scum line

    Sprayed it on and waited a few seconds and the stuff just wiped off. Worked great! I had tried many other cleaning products along with lots of elbow grease with little progress. Then I found this product online and ordered it with expedited shipping. I tried it out right away and am very pleased with how well the product worked. I am especially pleased that you don't need to worry about damage to trailer or wear a hazmat suit to use it. I will definitely be ordering more of this product.
