one of the two doors is very sticky. it seems that grease would be the way to go, but how? Or does it just get a shot of oil?

What feels sticky? The handle or the hinges? What happens is the parts rust up and start to stick. Spray down the hinges, lock mechansim, and under the handle with PB Blaster or WD-40. I mean a TON! Spray it down work the door close and open atleast a dozen time then wash the excess oil off with soap and water. Its unfortunatly messy but the only way to fix it. :rolleyes:

should have been more clear. it's the hinge.

spraying it with PB Blaster is what I was thinking, but was hoping there was some way to grease it.
