I have OLD style guns. For some reason they made them outta metal?
I have some purdy guns too. 3 handguns I have, have nickel finishes.
DONT....repeat DONT use Hoppes #9 or any other ammonia based cleaner on nickel. It will get into cracks you can’t see and deplate the nickel off of the copper under-plate.
I use Hoppes or other strong cleaner for most of my other guns.
Also.... be careful with 111 trichloroethane like gun scrubber around plastic parts. It can melt most plastics. (That’s for you glock guys )
Lots of my black powder shooting friends use something called ballistol. Supposed to be good for the bore and accuracy for you cap and ball folks. Supposed to make your BP guns shoot straighter too. I find it messy and tend to shoot smokeless or BP substitutes to avoid th mess, myself. But that’s just me.
I am a armorer for an agency that carries glocks. Gun scrubber has exactly zero effect on the plastic parts.
