I use it here and there for some projects I do - when I start running out I will order more!

I have a heavy build-up of marine growth on the lower portion of the pontoons on my 20' pontoon boat. Not sure what type of growth but it has a sandy consistency. The boat sits at a slip in a fresh water lake from May to September. The cleaner did not remove any of the marine growth. It did a good job of cleaning the other parts of the aluminum pontoons not covered. A long soak time do not make a difference.

I have polished aluminum wheels on my van. The front wheels got totally roached by the bad winter's salt & brake dust. I tried to get them clean with 3 different store brands with poor results. Looking for an industrial strength acid based cleaner I came across Bio-Kleen's Aluma Kleen. It arrived quickly & was packaged so that the shipper could not destroy the box & cause a leak. Following directions I sprayed the wheels, scrubbed a bit & hosed the Aluma Kleen off. Not much improvement but sprayed some more, scrubbed & WAITED for the cleaner to work. As it began to dry a little more cleaner & a little more scrubbing & the wheels were coming cleaner than they had been in forever. Happy, happy, happy.

This product worked great! I watched the how to video...very very helpful..

great product is so easy to use works great on unfinished aluminum
