So, I've had my rifle a couple of months, and put about 2500 pellets through it. The nice man at the shop said that I didn't need to worry about maintenance as they cover everything, however, I am certain that I should have a cleaning / preventative maintenance routine. I'm sure a rub over with WD40 would be better than nothing, but I can see about a thousand lotions, potion and lubricants on the market. Do I need to worry about the woodwork, or just the metal? My question is; what is your cleaning / maintenance routine, and what products are best??
