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 powder to water, not the other way.....

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