"What's in your parts washer?"
A dead rat.
Gotta clean that thing out one of these days........
Oh, you mean what kind of solvent!!
I never owned one since I had lots of friends with them. But, about a year ago I saw a cheap one at one of those tool sales and bought it.
I think most of the ones I have used had either MS or Kerosene in them, not sure.
But, this one was super cheap, made in china in one of their lesser quality factories, so I did not want to use anything flamable. It had all kinds of warnings about not doing so.
I was afraid the pump motor might detonate.
So, I filled it with Simple Green. Probably a mistake.
It did the job pretty good, but after washing several parts I noticed something strange.
I could not close my left hand.
It was not paralyzed, it just did not close any more.
I held it up next to the other one, and it was about half again bigger than it should be.
It was swollen more than you would believe.
Didn't hurt, itch, or even feel bad.
I turned a hose on it and started washing off the Simple Green. It did not seem to want to wash off.
No matter how much I washed it, it just kept sudsing up.
I could make a fist and foam would appear. I kept washing and scrubbing and gradually the suds went away, and the hand started looking more normal.
It was not a reaction to the stuff, it just had absorbed into the skin and swelled it up.
I still use it, but I make darn sure I use gloves when I do.
