Advice from some quarters suggests soaking the tools in a weak acid (vinegar, oxalic acid, citric acid etc.). I have been unable to obtain quantitative advice on the strength of the acid to be used and the soaking time for optimal values. Presumably, too short a time or weak a solution will be ineffective, whilst too long a time in a stronger acid may lead to undesirable etching. I have tried 8% acetic acid neat, but is it better to use a weaker solution for longer, or repeatedly with the removal of residual rust with a brass brush in between? 13 September 2019 at 7:47 am #10527 Peter CooperParticipant (Awaiting moderation) Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
