    My lock cylinders are getting sticky and wanted to know if anyone had any suggestions. I was told to stay away from WD-40 because of rust. Is that true? TIA.

    The WD in WD-40 is supposed to stand for Water Displacement or somesuch and i've never heard of it causing rust but maybe attracting dirt and clogging it up more. I've used graphite and it works sweet and doesn't attract any dirt.

    So, which one of you is the brains of the operation?
    To tell you the truth it's not exactly a "brains" type operation.

    I agree for all my sticky locks I use the graphite powder, it is incredible how well it works.[​IMG]

    There is a liquid spray graphite lock lube you can get. When you spray it into a lock cylinder, it flows the graphite in and then the liquid evaporates. It really works great. I can't remember the name but I see it for sale all the time. I have some at my shop, so I'll get the name and post it tomorrow.

    Do you mean sticky like there is old grease and dirt and other junk in there, or sticky because there is no grease and the internals don't want to move. If there is junk in there, I would rinse it out with some brake parts cleaner, let dry, then use the graphite spray.

    I just remembered the spray was in the back of my K5. The name of the product is Lock-Ease...graphited lock fluid. It's in a 3 oz. spray can and comes with the red tube like WD-40 does. The description says:

    Enters as a rapid penetrant, coating all lock parts. The special "carrier" soon evaporates, leaving a graphited long-wearing film. After evaporation, will not run, even in the hottest climates...won't harden in sub-zero temperatures. Recommended for every type of lock. It can also be used on tools, guns, fishing reels and other mechanisms.
