On rimfires ive been doing this for years.. Rimfires dont burn as hot as centerfires so carbon is usually not that big of a problem. But grit and grim is a huge problem with these guns and wd-40 is a cheap cleaner/lube so using it to lossen the grit and grim is a cheap way of doing this that wont hurt anything like some of the gun scrubes will.. you can use a old tooth brush or what ever to help those areas that have been packed like th bolt face and breech... but the air hose will remove 95% of it... then relube with clp or whatever you like and enjoy... guns are a hobby its not right to make it unenjoyable by having to spend the rest of the weekend cleaning it
People talk junk about W-D 40.
A little History:
Fascinating Facts You Never Learned in School
In 1953, a fledgling company called Rocket Chemical Company and its staff of three set out to create a line of rust-prevention solvents and degreasers for use in the aerospace industry, in a small lab in San Diego, California.
It took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40®—which stands for Water Displacement perfected on the 40th try—is still in use today.
Convair, an aerospace contractor, first used WD-40 to protect the outer skin of the Atlas Missile from rust and corrosion. The product actually worked so well that several employees snuck some WD-40 cans out of the plant to use at home.
A few years following WD-40's first industrial use, Rocket Chemical Company founder Norm Larsen experimented with putting WD-40 into aerosol cans, reasoning that consumers might find a use for the product at home as some of the employees had. The product made its first appearance on store shelves in San Diego in 1958.
In 1960 the company nearly doubled in size, growing to seven people, who sold an average of 45 cases per day from the trunk of their cars to hardware and sporting goods stores in the San Diego area.
In 1961 the first full truckload order for WD-40 was filled when employees came in on a Saturday to produce additional concentrate to meet the disaster needs of the victims of Hurricane Carla along the U.S. Gulf coast. WD-40 was used to recondition flood and rain damaged vehicles and equipment.
In 1969 the company was renamed after its only product,
WD-40 Company, Inc.
In 1973, WD-40 Company, Inc., went public and was listed Over-The-Counter. The stock price increased by 61% on the first day of listing.
Since that time, WD-40 has grown by leaps and bounds, and is now virtually a household name, used in numerous consumer and industrial markets such as automotive, manufacturing, sporting goods, aviation, hardware and home improvement, construction, and farming.
In 1993, WD-40 was found to be in 4 out of 5 American households (it seems everyone has a can or two) and was used by 81 percent of professionals at work. Sales had grown to more than one million cans each week.
OVER THE YEARS...
The most interesting piece of WD-40's history is the uses for the product, now numbering in the thousands. Over the years, thousands of WD-40 users have written testimonial letters to the company sharing their often unique, if sometimes just plain weird, uses for the product—many of which are shared in other parts of this Web site.
The uses include everything from silencing squeaky hinges and removing road tar from automobiles to protecting tools from rust and removing adhesive labels. But they get a lot crazier than that. Some of the more interesting stories include the bus driver in Asia who used WD-40 to remove a python snake, which had coiled itself around the undercarriage of his bus, or when police officers used WD-40 to remove a naked burglar trapped in an air conditioning vent.

WD-40 Facts & Myths | WD-40 Ingredients
I use W-D 40 mainly as a cleaner. I also use 3in1 oil.
3-IN-ONE Oil Corrosion Protection | Stop Rust, Lubricate & Protect where needed. I have also found that Slick 50 works good where heat is the problem.
I am sure there are better products out there.
But being older I just use what I know works.
