30% Hydrochloric acid

[Dude4ever]

Another acid question:
I got 30% HCl, bought in hardware store used for acid wahing of masonry.
The colour is yellowish, I have tested it by putting different metals in it, copper and solder dissolves OK in it.

Just want to know if this type is sufficient, and also if I can concentrate it more and/or remove the yellowish colour?

Thanks guys

That is what we use, no you cannot or do not need to concentrate it.
As long as it does not say something like scent free HCl.

OK, thanks I think I'm good to go then. Just have to wait 2 weeks for my SMB and nitric acid to arrive....
