Before you dash out and spend a fortune on 'Gun cleaning products', may I explain how I clean my guns. If the bores are really dirty and have plastic fouling in the chamber area, I spray some Phillips barrel cleaner down each barrel and then lay them flat on the bench whilst I go and have a cuppa. After some 20/30 minutes, I roll 3 pieces of bog roll together and shove into one barrel, repeat for the other barrel. Then push rod and bronze brush (Payne Galway variety) into barrel forcing the bog roll through at the same time. This is usually sufficient to get them clean, I then follow with a second rod and plastic jag, fitted with a further 3 pieces of bog roll folded lengthwise and shortened to fit barrel. Wipe the outside of metalwork with a micro fibre cloth soaked in car engine oil (preferably clean oil !). If the barrels have a centre vented rib, I spray them with 3 in 1 aerosol can oil (99p in pound shop) and stand on newspaper, inverting barrels after around 15 minutes. Wipe out the action and breech face with oil soaked rag, apply some Lucas red grease ( £6 off Ebay for a MASSIVE tub) to hinge pin and knuckles (the guns, not mine). Remove chokes, clean and apply Lucas red gun oil (£6 a bottle off Ebay). Spray stock with beeswax furniture polish (£1.29 Home Bargains). Job Done !
I only remove the chokes after every 5/6th outing for cleaning, I only use Phillips barrel cleaner IF there is fouling in the barrel. If it is raining, or looking like it may, when I am about to shoot, I spray the outside of my barrels with a 3 in 1 spray oil, wiping off the excess with a piece of kitchen towel before slipping the gun. I then spray the outside of the barrels, if wet, with WD40 after shooting, prior to the journey home. This has worked for me over the last 55 years or so and my guns can only be described as 'mint' condition. (according to those that I shoot with, anyway) Hope this helps, better to spend the money saved on cartridges, rather than overpriced 'gun cleaning products'.
