Alcohol flush

[Boley]

Thanks fellows! The "alcohol flush" worked great on a 1976 Benjamin 347 that had quit building pressure. A flush with 91% Isopropyl  Alcohol followed by an overnight soak and it was building enough pressure to blow gunk out. Application of "Secret Sauce" and another overnight soak, and it's back to full power. I'd bought the reseal kit a couple of months ago but have been too lazy to do the work. Will use that kit on another Benjamin sooner or later I suppose. I've had that 347 since 1976 and it was resealed about 5 years ago for the first and only time. You fellows have come up with something that can really work !

Tried it very cautiously on my Crosman 2100 with a 96% isopropyl alcohol (got it in Spain, can't be found in France) and the result was :
- No goo neither dirt on the paper I shot a few minutes after I had dropped some alcohol in the air intake. Didn't forget to cock the rifle before. Dry shot three or four times.
- Put 2-3 drops of Pellgun oil in the same hole (I hadn't bought the air tool oil yet).
- Then I checked the riffle accuracy at the usual 30m range : no change, just perfect.

I surely won't complain. Usually when I'm tinkering one of my airgun, there's always something going wrong. Not this time!

No need to struggle with injecting alcohol or oil into the air hole. Just place about a ½ teaspoon (I’ve gone heavier at times) above the plunger. Cycle the gun a few times & let it sit upright for a few hours or overnight. Gravity will send the alcohol into the piston where it does the most good. Same with the oil (secrete sauce or whatever none detergent you prefer), after you’ve blown out all of the alcohol. A few drops above the plunger. Cycle the gun & let it sit upright. The oil will find its way into the piston & other parts with regular use.
 
Once there is no longer any alcohol or oil dispersed onto the white rag I use Goo Gone to clean the inside of the barrel. I continue to swipe it with clean patches until it is completely dry.

No mysterey on the alcohol. Just regular rubbing off the counter alcohol.

One last tip...since your flushing with alcohol, use it to clean pins & pivot points (being careful not to drench wood). Those areas are usually just as bad...lube when done.

Thanks guys...actually had seen that one for some reason thought it was more involved...secret sauce didn’t work overnight by itself..will try flush but for backup ordered new brass valve and pump cup...

No...oil does not work by its self. How is it going to break down gunk? You might change your mind on the involved part after cycling the gun umteen times to clear it out.
