What can be used on the plastic parts and what should be avoided? I know some solvents can hurt the plastic. Is my Hoppes of to get on it? I don't get too crazy about cleaning my M&Ps, but like to keep them free of too much dust and keep the blast off the externals.

Soap and water works wonders.

Both Shooter's Choice and Gun Scrubber make spray cleaners that don't damage plastic or rubber parts. Spray it in, wipe it out. Completely evaporates leaving no trace. Personallly, I prefer Shooter's Choice but a can is a little expensive. Also, read the labels on your gun cleaning solution bottles, some state specifically that it's safe for plastics and rubber. I prefer the spray cans, because you can get in all the little nooks and crannies, that you might miss using a swab or brush or whatever.

Then you can clean your barrel with the cleaner of your personal choice, reassemble, and your done.

Hose it down with GunScrubber followed immediately with compressed air. Apply some Weapon Shield (or similar) grease to the rails and face of the striker block, and their oil to the other areas. Do this every few months (or 5000 rounds, whichever comes first) and your M&P will serve you for many, many years.

There is not much to cleaning polymer. I just use whatever solvent I'm using for the rest of the gun, and even then I just clean the fouled up front part near the muzzle. I second using grease on the rails. Oil seeps out pretty quick.

I use MPro7. The main ingredients are good to go on Nylon 66 aka Zytel polymer frames. My go to CLP is Otis O85, and for field lube I use Swiss made Skateboard Bearing lube. Its really runny and thin, but it works wonders for being a dollar a bottle.

I wipe the external grip frame surfaces with hot water/soap on a well wrung rag, because I HATE slippery polymer guns. I wipe the internal parts/surfaces clean with whatever gun rag is closest to my right hand at the moment.

Agree 100% on KRWiess' lube instructions. I use slide glide I've had forever (used to be a Sig owner).

I have used brake cleaner for years during matches. It works for my M&P's and problems. When I am home I use Simple Green or Purple Power and hot water. Blow out with my compressor and I am good to go.

Clean guns are great but there is not need to put too much thought into it.

I used Break-Free and CLP for years and then we were taught in the Police Academy we could use brake part cleaner on the steel parts because its the same stuff and its much cheaper. Break-Free is 10 bucks a can. brake cleaner is 3 bucks a can.

Just recently got some Froglube paste to try out. It actually works great on the plastic too. It made mine look brand new again
