I needed to acid wash my corroded and pitted aluyminum horse trailer floor. With EPA regs, could not find any place to do it for me, so I purchased this product. It worked pretty well, given the condition of the floor. I did need to use it at a 1:1 dilution to have any effect. also needed to apply a moderate amount of elbow grease. Used a broom to scrub as it foamed, and it helped quite a bit. Would use again

Works great on cleaning my semi trailer. It gets all the road grime and salt off usually one time. Rims takes a couple times over.

Had to apply a couple times times with light scrubbing, however it did a good job on my aluma klm trailer. 8 years of heavy use, sitting outside year round, and having only been pressure washed a couple times, I'm pleased with the results. Hope the glare don't cause a crash😎

Worked very well on my aluminum horse trailer. The trailer almost looks new again.

I used a 1:10 solution on my 12 year old aluminum horse trailer and my trailer looks like new. It did take a few applications coupled with pressure washing to remove the years of oxidation, but the dull aluminum is bright and shiny again. Highly recommended!
