Damn that is scary ...
A lot of the chemicals we use can pass through the skin also , brake cleaner being one of them. It builds up internally over time , with frequent use.
Had a mechanic buddy damn near lost his liver from spraying his stuff clean too much with that stuff. Docs thought he might need a transplant , if he could find one in order to survive. He got lucky and pulled through ...
Another point , rubber gloves , when used for chemical protection are meant to be disposable.
Learned that from a very good safety class our union put on. The chemicals do get into the rubber and the gloves are rated for "X" amount of time exposed to "Y" chemical. After that amount of time , the chemical is leaching through the glove and getting to you.
Point is , if you use the gloves and set them back on the shelf , two weeks later , when you put them on to wash the Bronco or whatever , you are exposing yourself to the chemical that is now INSIDE the glove.
Another thing to keep in mind ....
