Hoppes now makes a solvent called Hoppes Elite Gun Cleaner which is supposed to be gentler on "finishes". It's not cheap.

Ed's Red Bore Cleaner is still my favorite, equal pasts:
ATF - Dexron type
Kerosene K-1 type
Mineral Spirits - low odor
Acetone

Note , you can omit the acetone for a less agressive bore cleaner and equal parts ATF and kerosene make a great light lubricant.
Equal parts ATF and acetone make a super penetrating oil , use in place of Liquid Wrench.

I recently purchased 1 quart of all 4 items for ed's red from wally mart. They had everything, the gallon of cleaner came to under $20.00 ($17.67 if I remember correctly) not a bad price for a good cleaner.
I'm not fond of some of the "new" finishes S&W uses , it should hold up to gun solvents...but it doesn't. That's just not right !
