I hope no one gets the idea from this post that it is OK to use lacquer thinner, mineral spirits, MEK, etc. for hand cleaner. None of this stuff should be allowed to come into contact with your skin. Nitrile gloves are a must not an option when handling this stuff.
The MSDS (material safety data sheet)for just about anything is available at
this web page . For your health, look up any chemicals you may be using and heed the precautions.
