DISHWASHER SOAP.
Never, under any circumstances, consume a sleeping pill and laxative on the same night.
I have put an entire m&p 2.0 in an ultrasonic with Slip 2000 Ultrasonic cleaner solution diluted to a 4 to 1 mix with water. I took off the slide, barrel, and recoil spring out and then the entire grip with all controls in.

I have also used simple green diluted but this stuff is for my really dirty stuff - like my 22 pistol after a full year with no cleaning.
Come out fine. The polymer was slightly discolored in some spots when it first came out but after oiling it all (yes, even the polymer grip) it looks like new.
NOTE: Ultrasonic cleaning require more attention to post cleaning oiling/protection that normal gun clean. If you clean a pistol without full disassembly, you need to make sure you oil everything and about the only way to do that with things still assembled is with some sore of spray on oil that can get it all the cracks. I then took my air compressor and lightly blew the oil around to make sure it got it in all the cracks.
