I've been reading through web pages and old posts about electrolytic rust
removal, and apparently using stainless as an electrode is a no-no due to
toxic waste concerns. As such, a "graphite rod" is the preferred thing.
My question is, when they say "graphite rod" do they mean any specific
type of graphite rod? Could I use rods for carbon arc welding, or
graphite rods used for EDM? Looks like Enco has graphite EDM rods on sale
(or at least they did a little while ago) and I've been wanting to try
removing some rust with this technique, but I'm not sure if these are the
rods I should/can be using or not. Thanks in advance for any assistance!
