Newbie here, and 617 is my first handgun. Have been reading the forum for a while now, and hopefully can start contributing.

I typically clean every 200 to 300 rounds since the revolver gets visibly dirty no matter what ammo.
Here is how I clean my 617:
1. Wipe with a rag to remove debris and spray all visible surface with froglube solvent. This includes cylinder and bore. Let it sit for 2-3 minutes.
2. Look for any visible carbon or lead deposits around the forcing cone or on the cylinder faces. If present use lead free cloth to wipe them clean. Knock off with pro shot pick and scrapper. Typically everything should come loose. For stubborn deposits use bronze brush to scrub clean.
2. Tie a sock around the firing pin mechanism. Dip brass bore brush in solvent and run in through the bore from muzzle end. Ensure it comes out from the forcing cone all the way (do not stop halfway and pull it back). Repeat a few times.
3. Similar process for all 10 chambers in the direction of travel. Repeat if necessary.
4. Using a toothbrush dipped in solvent clean the star and scrub all steel surface. Make sure to clean beneath that mechanism since it traps lot of powder.
5. Run dry patches through the bore and chambers until they are clean and, well, dry.
6. Wipe with a clean rag to remove all debris. Use q-tips around the star and difficult places to lift the debris.
5. Using a hair dryer heat the steel frame. Medium heat on low speed for about a minute does the trick. You can put it in the sun for a few minutes as well. This is for rapid absorption of the froglube clp paste.
7. Apply the clp paste over the surface, a few drops suffice since they quickly melt and become liquid. Apply a few on your hands and rub all over the frame including trigger and hammer (I generally cock it and apply). Put a few drops on dry patches and run them through bore and chambers. Let it sit for 20 minutes.
8. Run dry patches through the bore and chambers, and scrub the excess with a clean rag. It should look shiny but not excess oily. Clean the grips since it may have clp or the solvent trickled down.
All in all under an hour and the gun should be squeaky clean. I moved to froglube since my 8 yr old likes to help and frog is non-toxic and safe. Shall upload my recent cleaning result later tonight.
