block treatment

[David Costello]

guys I'm thinking of acid dipping my block at home, I've been told the acid they use for dipping blocks and the like is just caustic soda and water.  does anyone know what ratio to mix them? (how many parts soda to how many parts water etc) how long should I leave a block in for?   can the rods be dipped too? mine are covered in crap from lying around the workshop I got em from.   Dave --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
