My brother-in-law brought me 5 19# mustang injectors from his dealer, they have been sitting around awhile and need to be cleaned. They were working when pulled. The question that I have is what is the best thing to soak and clean them with. Some parts cleaners say not to soak rubber or plastic parts, B12 is one of them. I thought about Seafoam, the label doesn't say anything about rubber or plastic. I'm worried about the inside of the injector being gummed up.
thanks,
JR
