Yeh..what Kev 74 said: Muratic acid will disolve aluminum in seconds, fills your shop with strong fumes, burns your eyes, and makes you loose your last meal/beer. Muratic acid works okay for removing chrome from steel parts..just do it outside and watch how long 'cause it will eat the steel also. I think you have to watch how you dilute muratic acid also..acid in the water or is it water in the acid? C.R.S.
Some of the chemicals us old guys used are "controlled" due to them being used in meth labs etc.
