"cleaning the bolt" - remove it from rifle - wipe down the bolt exterior and where it rides within the rifle - should feel nice and smooth to cycle. Mauser and Win 70 usually easier to dismantle further to get the firing pin and it's spring out where you can see it - much written "how to do" for Lee Enfield on the milsurp website - look for articles by Peter Laidler - no doubt has been written up by others, as well. Is typical, I found, for some makers to coat firing pin spring or to fill the bolt body with grease - maybe a preservative? - in cold Sask hunting seasons, that grease often "jells" or gets "stiff" - slowing down that firing pin - can get misfires in the cold. I usually dismantle completely - once - use solvent to remove all grease - I used to use gasoline as solvent - now I use "paint thinner" Varsol - re-assemble and paint all with 0W20 motor oil - just to inhibit rust forming - I do not use any rifles enough to warrant lubrication for "anti-friction" purposes - except my bolt action rifles get a small dab of "white" grease on the cocking cam, and on the rear of the bolt locking lugs.
"wiping down" - typical here to use discarded dish towels - cut maybe 15 cm x 15 cm square - or use folded up paper towel - dribble on a half dozen drops of motor oil or ATF - wad it up and let set - like over night - just about enough "lube" left behind when wiped on metal to clean it. I found oil and grease about a "magnet" for dust and crap - so, to a point, I use it sparingly. Tends to require periodic inspection - which was never done among household guns when I was growing up - was several that I am sure never saw a drop of oil or a wipe down for 10 years or more - but not likely to have been fired 30 times in that period either. WAY more damage done to them by the corrosion that formed, versus "using" them - did not seem to be an issue for $15 surplus 303's back then.
I have read that some types of semi-auto rifles want to be "soaking, dripping wet" with oil to function properly - I have no experience with those.
