[Amc-list] Citric Acid Rust Remover - Follow up Post with modifications

[Greg Taylor <amundaza@xxxxxxxxx>]

Hi Everyone,
  This is a follow-up email to last week?s post on using Citric Acid as a rust remover.  After testing it out on the pistons I posted photos of, there are some post acid-bath procedures that I have modified.  Originally, I had simply rinsed the de-rusted parts in warm water and let them air dry.  This proved to be insufficient in cleaning the parts, as they developed typical water contact surface rust in areas, during the drying process.  They also were ?sticky? with a dark grayish coating from the rust conversion process.
   
  So instead, I took the de-rusted parts, soaked them in a hot water bath with laundry detergent (was readily available).  Next, I scrubbed them with a plastic bristle dish washing brush from the dollar store, in the soapy solution, rinsed in hot water and towel-dried best I could.  Then, I followed up with a blast of compressed air to blow any more water off.  Finally, I sprayed them with Wrench-ease penetrating oil, to preserve the now clean, rust-free metal.  This procedural change has resulted in preservation of the parts, so that rust would not form again.  FWIW, the cast iron parts re-rusted much more than the steel parts.
   
  Sincerely,
Greg Taylor :)  <><
