We've a Moen faucet for the kitchen sink. Years, maybe decades old. The faucet was dripping last year so I replaced the cylinder with a Moen cylinder. Solved the leak but the handle would not stay up in the on position. Returned the Moen cylinder. Bought an aftermarket cylinder from Home Depot. Handle stayed up. Now, a year later, the faucet is very very difficult to turn on, as if the cyclinder needs to be re-greased.
What type of grease is compatible?
1) the cylinder looks like this: http://www.homedepot.com/p/100051867
2) found a possible duplicate: What can I use to lubricate a new kitchen faucet no longer turns?
