As part of an overall effort bring our GW-EFI in spec, I want to clean the IAC valve. AFAIK, sloshing around carb cleaner or brake cleaner, and blowing everything out afterwards should get the job done. Or...?

I'm always nervous using Carb cleaner around electronic parts. I tend to start with Contact Cleaner, and move to Brake Cleaner if needed. Could be I have nothing to worry about, but, am remembering Carb Cleaner from days of old and the new stuff isn't the same. Think Think
Plastic damage is another thought.

I tend to use WD40 as a cleaner and then lubricate with synthetic oil.

I like hooking it up to a 12v power supply and activating it while spraying my preferred cleaner, then using an airhose, blowing it out.
