I bought an AAC Prodigy about two years ago and hadn't had it home a week when my Dad asked to borrow it to shoot the tree rats eating the grand kids swing set in the back yard.... He is on my trust so sure, why not. About 10 days ago I finally got my suppressor back to shoot a local match. When the match was over I decided to clean it before giving it up again but it is frozen shut.

Any recommendations on what to soak it in to break up the crap inside so I can get it open? It is an all aluminum can so I can't use anything too caustic.

Thanks!
