I use to use simple green, started using it on my aluminum trailer (1951 Royal Spartanette) then was told by a bunch of trailer enthusiasts, that it will corrode the aluminum and to use the purple power instead. I also use gasoline as a solvent and then use it as weed killer when done. I follow up with the purple power after that.
