MP60s - can't get nozzle/screen off

[nezw0001]

I have four MP60s in my 450. I routinely soak them in vinegar, take them apart and clean them. This time I can't twist the nozzle/screen off. What should I do? I don't want to damage the screen.

Following. Have had the same issue with an mp40 close to a year now even after vinegar and acid baths it still doesn't want to break loose.

I notice the MP60 is turn clockwise to open. Do not use vinegar on the magnet. I mix 50% vinegar and 50% water then soak for 15 min but that enough to crack the magnet. I just open RMA and sent an wetside with crack magnet for repair. You can soak all other part of the wetside but not the magnet.

I ended up breaking it off and buying a new one. The new one goes on/off easy. There didn't appear to be any build up on the old one.
