I use about a 10 per cent or less ferric chloride and scrub it soon with wet steel wool to take the excess crud off the barrel. After boiling I use a ferrous sulfate Wash if I am using logwood and also scrub it down with stel wool and ferrous sulfate(copperas). Both of these improve the definitions of the steel and Iron.
