Being your a gunsmith, what would you recommend for cleaning my 38s?. In the police academy they gave us a nice revolver cleaning kit that came with everything you need. And I often pondered if they used WD40 today for cleaning the chambers and barrel etc, or do they still recommend the solvent in that kit with the small wipes.
PS: What do u think of this cleaning kit?
Or should I go with a better one, I don't usually fire my weapons much.

Personally, I like the categorical (pistol, rifle, or shotgun) caliber universal kits by Ruger. The rods are really nice. The hopes is ok, but their oil isn't all that great and there are better solvents. I like Lucas gun care lubricants and solvent.
The big ticket for long term revolver health is to periodically (once every few years if you shoot regularly but aren't putting cases of ammo through it) take the side plate off, take THE ENTIRE movement out, clean it, and put it back with grease and oil in the appropriate points. Most only ever use oil; btw, the lucas gun grease is AWESOME. I use it in everything, including my ARs.
If you find the cylinder rotation gumms up, don't take it fully appart. Take it as far apart as you can without tools after the cylinder/crane assembly is seperated from the frame. Boil it in water, yes water and then dry with shop air. Brush away any fowling with a stiff bristled nylon brush followed by an over night soak in kerosene. Exercise the extractor while submerged in the kerosene. Let the kerosene dry out and then re-oil with your choice of gun oil.
As far as wd40, its not real great at anything in the firearms world other than displacing water. Its in the name after all, Water Displacing - #40 more cleaner than lubricant.
There are some solvents that turn blue with copper/brass exposure. They are the best for determining when a bore or chamber is CLEAN as the patch will no longer change color. Keep in mind these require a special rod, otherwise the solvent will react to the brass left behind by the rod itself. Thats more for precision rifles, your revolver wont mind if a bit gets left behind. After solvent, I flush the bore with denatured alcohol and then run a patch of light oil through the bore for storage or before taking to wet/humid weather.
