You want ~30% w/v, i.e. 30g made up to 100ml, or 300g up to 1 litre. With ~0.1% HCl.

No. I mean make 30g up to a finished volume of 100ml, that's %w/v. Hydrochloric acid is sold as a pool (swimming) additive.

It needs to be a bit acidic I believe, but not having done this you could always try without. (running out of knowledge about etching...)

Add the chloride to the water until it looks like store bought stuff.
