slide gear & rack

[garyka]

I have been spraying slide lubricate on the gear & rack periodically and it doesn't seem to be doing anygood,they are still showing rust.Why can't good old fashion grease be used here,I don't see how this could come in contact with anything inside of the of the monty.I thought I read somewhere not to do this,it could get on the rugs.I can't see how unless I'm missing something.Thanks for any input
