WD 40 did that........ never seen that before, think there is more to that story. I use WD to protect and clean many different things.
I too have used WD-40 on lots of steel / iron surfaces left in unheated areas and never experienced gumming. Looks a lot like what I have seen from vegetable based oils. Sprayed Pam on some CI cookware left in an unheated shed, similar gum formed on them. Since then only use lard or tallow. Just my $0.02 for what it's worth.WD 40 did that........ never seen that before, think there is more to that story. I use WD to protect and clean many different things.
OMG ! You used Acetone ! That is such Nasty stuff , you're never supposed to use that around machines ! It's vapors will melt paint , vaporize metal , kill you instantly ! Oh , and it will explode even with ventilation fans on. You should only ever use kerosene .WD-40 will indeed leave a hard, molasses-like layer on parts if left to dry and accumulate.
the ways are pristine underneath that layer of guck.
I found that Acetone gets it right off.
thank you. john. i thank every one for there comments .John,
I moved your thread under the other Questions & Answers Forum. Ken
When I was in high school I worked in the paint room of a furniture factory. Acetone and Naptha were the big ones. Bare hands dipped in a bucket of acetone with a rag will dissolve laquer no prob. LOL. No ventilation in the pump room when we changed out 55 gallon drums.OMG ! You used Acetone ! That is such Nasty stuff , you're never supposed to use that around machines !

....well , at least that is what I was schooled on here ...lol
WD-40 will indeed leave a hard, molasses-like layer on parts if left to dry and accumulate. Here is a shot of my Emco lathe when I got it. Hard to believe this lathe had only 100 hours on it and the ways are pristine underneath that layer of guck. The PO just shot it down with WD-40 after using it and left it to accumulate - I have to wonder if he had a brain in his head. After a lot of trial and error, I found that Acetone gets it right off.

WD-40 is fine for cutting but do clean your lathe after you're done. A-9 works the best for me when a fine finish is needed or when tapping or thread cutting.
