Made my 16 year or horse trailer look almost new. Some areas required a few applications, but with minimal scrubbing the dingy oxidized aluminum was bright and shiny.

In the past I have used the Napa brand that’s is made with HF Acid this product is not very safe and Aluminum Trailer came out great with little effort , also shiny . Will buy again.

Got this to acid wash my almost 30 year old horse trailer that we personally have owned for 20 years. It has NEVER been acid washed and was brown and dingy. I spent 3 days working on the trailer and I cannot believe how nice the trailer looks now. No, it doesn't look new (never will) but it looks pretty darn spiffy now!!

The Acid worked as promised. I have aluminum rims on my Suburban and after the winter chemicals on the road destroyed the finish, I sprayed acid on the rims, let the acid etch the aluminum and hosed them off recapturing the bright rims once again!

Thank You Bio-Kleen

I was using the dish washer to clean the elements. The elements were getting more and more oxidized. The elements were starting to arc. I placed a quart of this cleaner in 14 gallons of water. Enough to cover the elements. It foamed and gave a scary odor for a few minutes. Black goo formed at the top of the liquid. However, the aluminum elements are bright clean and don't arc. The black goo was difficult to remove from the side of the cleaning tube but eventually came off.
