We still use the leaches here and muriatic acid is a common labeling for off the shelf stuff at stores like HomeDepot and Lowes DIY type stores.

It'll bring the pattern up as will most any acid. It'll etch as well just like any acid will. Some more & quicker than others.

I still blue or brown and bring out the pattern w/a very weak ferric chloride dunk, rinse and wet carding betw rusting cycles.
It's not fast but it's not a knife blade either.
