Grohe Grohmix Stuck Cartridge - Removal Tips?


I am trying to remove a grohe cartridge and have been able to do it. I used a 24mm wrench (recommended by Grohe)and channel locks to try turn the nut and managed to strip it. It seems that the brass colored nut is made of some soft material. I have tried spraying pb blaster penetrating oil, 50/50 water vinegar mixture and tapping with a hammer over the past 3 days. Nothing is working to break this stubborn cartridge loose. Any suggestions will be appreciated. Grohe support has been wonderful and helpful by sending me the parts under warranty.

I have attached a pic for your review.

It could be a left handed thread & you turned it the wrong way.
