I would recommend a barrier cream when handling any of these products. That will protect the skin - an organ in itself and make removal somewhat easier.
In my workshop I always apply barrier cream if handling any liquid product. Seen to many friends in the Engineering business suffer from skin ailments and much worse.
I knew someone who saw a brave salesman coat his hands with barrier cream then dipped them in a container of nitric acid! (BTW, the guy who told me was not given to telling BS).Barrier cream is a new idea for me, what brand are people using and how do they hold up to oils and grease?
Stoko ARRETIL Barrier cream . I finish hard wood floors we use it when staining. Works great washes off with soap and water. I highly recommend it. Use it to keep grease off when woking on the jeeps too..
