Decent quality grease gun?

   / Decent quality grease gun? #81  
I asked this somewhere before, but don't recall if I saw an answer or not. How do you clean an older gun with some of the grease hardened up? I have two or three that need to be taken apart and cleaned, including the hose and tips. Can they be soaked in Mineral Spirits or similar? Air to blow out the hoses?

Haven't cleaned one out my self, but I always have a bucket of diesel around used to clean parts, guess I would toss it in there and soak a while
