Vintage guns cleaning question

[brewbear]

Hi all,
I just received a Crosman 150 that looks good on the outside.... the inside is another story.
First off, I'm a novice at this so, I made my second mistake - while I was trying to take off the rear sight, I was fighting the jammed screw. I tried my new set of gunsmithing screwdrivers and managed to break the tip on the flat blade screwdriver while also marring the screw top. I stepped back, let loose a few choice words and then put several drops of WD-40 over the offending/stuck screw. About 30 minutes later it relented and came off not without putting up a fight. I gave a try to the screw holding the barrel to the compression tube and I could tell it was gonna put up a fight just like its brethren so I used the WD-40 approach giving it about an hour to work its magic. It came off without too much effort and now I got a good look at the inside. The good news, no visible rust... but there's a ton of sticky, goopy stuff coating everything.
  How do you gents clean up that stuff? I can only surmise it is dried up Pellgun oil or something like it.
All advice is welcome,
Thank you

Mineral spirits. Denatured alcohol.
 Brake clean but it's nasty stuff. Keep it off your skin and out of your lungs. Can ruin some plastics.

That's what I use. Aerosol carburetor cleaner first choice or brake cleaner. Remove the plastic grips first.

Throttle body cleaner is good.  It's much better for plastics than brake cleaner (as many throttle bodies are plastic these days).  If you're replacing the seals and pull all the plastic off the gun first you'll have more options.  Brake cleaner is very bad news for seals.  I usually use 80% isopropol alchohol.

Luck,

Carb or break cleaner are the most effective,  but I'll often use simple green or purple power I think it's called degreaser.

As mentioned keep the good stuff off your skin and any plastics.

I too use rubbing alcohol or also Goo-Gone works.

I better get a gallon of isopropyl alcohol then, though I'd rather get the ethanol kind.
Scott, do you know someone that can service a Crosman 600?

I will let you know as soon as I find one.
