Cleaning old PD injectors

[Voluble]

Hey all, has anyone had any luck cleaning old PD injectors? I'm trying to get my spare set to work in my BEW, but they have been sitting wrapped in bubble wrap for the last 2 years or so and I couldn't get the car to start with them. I currently have a bad injector in the car, which was a used set I sent off to get rebuilt, and I'd like to get my spare set up and running. I spoke with Franko6 last month about new injectors and he mentioned that if they sit for a while they can get gummed up. Should I soak them in a particular solvent/other fluid, or get and try an ultrasonic cleaner, or anything else? I'd like to avoid sending them off to somewhere if I can.

you might try soaking them in liquimoly diesel purge. Be mindful of the electronics in those injectors

I'll try it out, thank you!

I haven't looked at these injectors to know how much can be submerged, but I've had very good luck cleaning steel/brass parts by soaking in Hoppe's #9 gun cleaning solvent.
