OK, so after convincing people that i'm not a lunatic I managed to buy the 32% strength HCl.
I diluted with 50% water so about 16% strength, this stuff stinks.
I laid the steel in the solution and it does bubble away so to speak, but it seems to take longer than 5-10 minutes.
The finish I get is like a gun metal grey colour, is it possible to get a shiny metallic finish? |
