Pleased with the product. I would like to save money by buying in bulk and re-filling the small bottles.

Works great! Had to do 3 applications to the really bad build up spots but all in all the product works great! I'll be cleaning yearly for now on. The job that I did was 13 yrs old.👍

We used this as the 2nd step to clean our boats pontoons....it took off about 5 years of algae/staining and made the pontoons look great.

Great for snowmobile tunnels and bare aluminum works great highly recommend.

Once again, after purchasing Aluma Kleen, i have my 20 year old pontoon boat looking new again. It is relatively easy to use, simply apply with a wet towel or sponge, work it into the metal, allow it to soak into the surface for around five minutes, then hose it off and wipe it down with a clean towel.

I am truly glad and appreciative that I have found this product two years ago, and will continue to use and order it in the future. By the way, if you have chrome wheels on your car, try Aluma Kleen on them too. You will be very pleased..
