Wow...this hits close to home for me. Right out of high school, I was working at an auto dealer in Anaheim...and since I was low man on the totem pole...I was "assigned" to wash all of the shop floors in the safety kleen solvent with a mop...then squeegee them dry. I, too, washed my hands in the solvent first...then with mechanics hand soap....when I was done working on cars.
Let us know how you are doing, Joe.
