You're right not to use Hoppe's on a nickel gun. Other than above advice, a lot of us like Eezox and also Breakfree CLP is good. Lots of folks use Renaissance Wax too.

Agree...let's assume it's not scratched, otherwise Flitz can be used GENTLY to remove slight surface scratches. I also use Eezox (wet cleaner/dry preservative & protectant) and after it's dried will use a microfiber cloth to remove any excess to assure I have a nice clean surface, then I'll use Ren Wax to bring out the brilliant shine. Never use any product that has ammoniates as an ingredient as it will eat/loosen the nickel plate. As an aside I use the Eezox and Ren Wax routine on all my Colts and just finished up my '66 Python...man o man what a difference from oils. It's breathtakingly handsome. Having some 30+ Colts I am still playing catch up as I'm rather OCD on cleaning and got behind on a couple dozen for the wax application. My bad, nobody else to blame

The bore and cylinder can be cleaned with CLP or any non ammoniated cleaning agent for firearms. Brass brushes are softer than nickel but as with any type of metal brush care should be taken near the muzzle and the cylinder face where it's finished as you would with any firearm. Some folks do use Hoppes #9 being mindful to immediately wipe any overspray/drips off but I err on the side of caution and don't use that solvent on any of my nickel firearms. Cleaning inventory here is Kroil, CLP, Eezox and Ren wax for the outside finish after I'm happy the gun is clean.
