I clean and polish my barrels after I buy a new air gun. I shoot them and test things for a while, break them in thoroughly and get them all dialed in, tuned and shooting the way I like. I kind of use this as my baseline. Cleaning, polishing, waxing and lubing are all different processes that can be used alone or in conjunction with each other. There are lots of different cleaning methods, lubricants and waxes that can be applied a plethora of different ways. Everyone has their own favorites as I’m sure you’ll see. Lol
After I have a good general understanding of how the gun shoots and it’s dialed in the way I like, I will wax the barrel with Renaissance wax and then lube my slugs and pellets lightly with Silicone formula WD-40. Some slugs and pellets will shoot quite a bit better and faster, others, there isn’t much difference at all. There is never a decline in accuracy or velocity though and the time between cleanings increases greatly. I hardly ever have to clean my barrels other than a quick pass with the patch worm and a tad of cleaner followed by a couple of dry patches.
There are quite a few different waxes you can use and they can even be applied differently. Some people just slop paste wax in the barrel, let it dry and wipe out the excess. To get the full benefit of waxing a barrel, you have to use a quality “hard wax” and really work the wax into all the microscopic grooves, blemishes, scrapes, scratches, imperfections and pores of the barrel so there is a perfectly smooth surface. That’s the point after all and it definitely works!
