You can rebuild your Moen (and other manufacturer's) faucet valves by
cleaning the existing parts well and then reapplying the RIGHT KIND of
o-ring grease. Unfortunately, places like Home Depot will mindlessly
sell you "plumber's grease" in little white tubs from companies like
Rec-O-Seal which are NOT for use on rubber, but don't say that
anywhere on the container. These petroleum-based greases will cause
the valve to stick if not used for a couple minutes, although if you
work the stem it will temporarily appear to be well-lubricated.

This is a myth.

Petrolatum (aka petroleum grease or petroleum jelly or Vaseline) attacks
natural rubber, but O-rings are not typically made from that. It does not
affect Buna-N (nitrile) rubber, which is what plumbing O-rings are
typically made from.
