What kind of solvent should be used to clean a air rifle?

I've had excellent results for many years cleaning my airgun barrels with WD-40. Removes light rust, loosens and lifts lead flakes, cleans pellet release agents left behind, and contrary to the myth, it does not damage orings. A few wet patches followed by seven dry patches, dozen shots to re season the barrel...works everytime.
 
I had a bottle of Ballistol that had a bad cap. Stored inside 70-75 degree constant. After a short while the liquid crystallized. I have worked maintaining equipment for the past 45 years. I have seen lots of oils get hard. But never this fast. I no longer use Ballistol. Watch out with Kroil it will not protect your firearm bore from rusting. It is a great cleaner I use it on anything I want to clean throughly. Then apply a protective coating of oil.

I tried Ballistol once, theres something in it that is an irritant for me...instant coughing and headache.

Interesting you mention Kroil and rust prevention..I remember reading multiple corrosion tests performed by hobbyists and WD40 never topped the list but it did pretty well and in all of them Kroil didnt Fair well. IIRC, CPL usually had excellent results for longer term protection with a wipe on type.
 
Agreed, Kroil is a poor rust inhibitor. This battery of tests convinced me to try Frog Lube and it was a game changer. Stubborn stuff that was prone to flash rusting remain in pristine condition, even with a fair amount of handling.

thx! I'll check out the Frog Lube.
 
Since i have switched from JSB pellets to JTS/AEA, i have noticed that the leading is more frequent and a little more stubborn to remove.
Currently, i am using Bore-Tech Eliminator for cleaning. I will pull a wet patch ..wait a minute ..then pull another. I usually double-up the patches for a tight fit through the bore.
The product is odorless(take that Ballistol), non toxic and doesn't stain and cleans out lead better than other products i have tried
Frog-lube sounds interesting
 
Hmm...interesting, internet search is indicating Frog Lube is coconut oil with some additives. I tossed an old jar of C-Oil out a last year. Maybe I should have been thinking repurposing rather than disposal. :)

That bore tech eliminator is advanced formulation for stubborn barrel fouling. That's a "good to know" item if the WD40 ain't getting the job done.

Thx!
