I used to acid wash a dump trailer that I pulled. Not my favorite job. I did my flatbed a few times also. Glad I don't bother with that anymore.
Muriatic is a weakened Hydrochloric Acid [HCL], Aluminum dump trailers u use Hydrofluric Acid to 'brighten' aluminum, still nasty stuff especially on windy days.
