wear rubber gloves, use a plastic or glass container for dipping the brush into

Acid cleaning the bench seat frame



using baking soda to wash off the bench seat frame



I like to follow up with a wire wheel on a 4.5" angle grinder (good high RPMs) a lot of guys use a drill but that is not even close to being as effective

these took five minutes to wire wheel





KRYLON only no primer



and yes the acid got into the nooks and cranies, manual hand wire brushes help, flat screw driver as a scraper helps, use what ever you gots bro
