Use cleaners like Breakfree CLP or MPRO-7/Hoppe's Elite which are the safest on the clear coat finsih. Don't use Gunscrubber or other similar harsh degreasing solvents. Hoppe's #9 is okay as long as you don't soak the gun in it.
If someone has no interest in newer S&Ws, why would they even bother to post in this thread about S&W "greed" and to state their lack of interest in them. What a waste of bandwidth. I suppose they want a cookie for making their opinion known in a thread that did not call for it.
