Re: OT: Anodizing aluminium ...

NaOH (Sodium hydroxide aka lye aka drain cleaner) is mainly used to degrease the part, gets that last bit of crap off. ? It’ll strip the oxide layer off as well, and giving the part a slight etch probably isn’t a bad idea.? It’ll eat the part completely if left in too long – try it with a drink can.? You wind up with the plastic layer. ? Tony ? ?
