Mine was stuck fast when i cleaned it out a while ago, I am having it looked at.

 

LPS 1 its a drylube with no silicone and is top quality. will not attract dust . long lasting lube properties. about 10 dollars a can. can be used for door hinges and what not. will not hurt paint. have to go to high end auto parts store like NAPA or a good hardware store. it has many uses so its a good investment.
