You can lubricate your Moen shower cartridge as long as you use silicone-based grease. Do not lubricate it with petroleum-based grease, as it can damage the cartridge’s rubber seals.

Experts usually recommend lubricating a new Moen shower cartridge if you’re replacing an old one. Doing this is crucial to ensure that the next time you change your cartridge, you will be able to pull it out quickly. Although shower cartridges are usually pre-greased, doing this as an additional step will help you.

Different shower issues, like a stuck shower handle, also call for lubrication. If you want to prolong your shower cartridge’s lifespan, lubricating as part of its maintenance is the way to go.

Now that we’ve clarified that lubricating a Moen shower cartridge is safe, you can proceed with the process. Before you start, turn off your home’s main water valve. Then turn on your shower to see if water is still coming out and to release some air.

Older Moen shower models have a plastic cap, so remove this with a flathead screwdriver. Then you’ll be able to unscrew the shower handle using a Phillips screwdriver.

A Moen shower handle with no plastic cap will probably have a hex nut under the handle. You can take the handle off by using an Allen wrench on the hex nut.

2. Remove The Escutcheon Plate 

After removing the shower handle, take out the screws on the trim using a Phillips head screwdriver. Unscrewing this will give you access to the sleeve that protects your shower cartridge. Once you remove the screws, pry the escutcheon plate off the wall with a flathead screwdriver.

3. Pull Out The Sleeve

With your pliers, remove the clip that holds the cartridge.

5. Get The Cartridge Out

Using your pliers, twist the nut to pull the cartridge out. If the cartridge is corroded and difficult to remove, apply WD-40 before twisting it out.

6. Lubricate

After removing the cartridge, it’s finally time to lubricate. If you plan on reusing the same cartridge, clean it with a paper towel before directly applying the silicone-based grease. If you have a new cartridge, you don’t need to clean it. You can immediately apply the lubricant.

7. Reinstall The Shower Cartridge

To reinstall the shower cartridge (old or new) after lubrication, you only have to follow the steps above in reverse. Just put the cartridge back, ensuring that one of the cartridge’s ear holes is on top of the valve body and the remaining one is on the bottom.

Then put the retainer clip or bolt back and check if the cartridge’s ear holes are in the correct position. Finally, reinstall the tube or sleeve, screw the round trim plate and escutcheon plate back in, and your Moen shower should be ready.
