I was just wondering if anyone can help me with the best way of removing the anodizing from my zaskar as it has had a hard life and is looking tired now. and us ut possible to get it re-anodised
The anodising is basically a skin of aluminium oxide on the surface of the metal. Sodium hydroxide, aka caustic soda, dissolves it. Be careful though, it's nasty stuff and if you're making it from crystals add crystals to water not the other way round - it's very exothermic .
