I'm glad you asked about mineral spirits. In this whole thread I never heard a caution about it but on the back of my can it says it's pretty bad stuff. Starting with, and I quote, "Danger! Vapor Harmful. May affect the brain or nervous systemcausing dizziness, headache, or nausea. Causes eye, skin, nose and throat irritation. Warning: Use of this product will expose you to benzene which is known to cause cancer and to toluol which is known to cause birth defects or other reproductive harm." It is also highly flammable. If you spray it use an approved respirator, etc. So, don't wash your hands with it, don't breath the vapor. Wear nitrile gloves and make sure you have lots of cross ventilation while using it in any manner.

Be careful out there!
