I just pulled 4 transmission solenoids from a salvaged 1994 LS400 & am planning to replace my worn solenoids with these

Can anyone recommend a safe cleaner to use on these solenoids? I saw a thread where someone used CRC MAF cleaner, but am wondering if I need to use a cleaner that will not affect the electric connectivity of these parts? OR DO I EVEN NEED TO WORRY ABOUT THAT ISSUE?

Any suggestions would be greatly appreciated; soloing this job this weekend, thanks.

I use CRC PF Precision Cleaner. This is made and recommended by CRC specifically for sensitive electronic parts. I use it on SMT electronic assemblies. It's specifically rated as safe for relays, coils, motors, and so on. Those parts mentioned use the same self-bonding enamel magnet wire found in solenoids. This is what I used to clean flux of my ECU's PCB (do not use isopropyl alcohol for that!)

THANKS FOR THE RECOMMENDATION 700Bones!

I just purchased a can of this cleaner (at $45.00!) and based on your information and the cost alone, I think this must be the best cleaner on the market particularly for my application.

Plan on replacing the now cleansed solenoids this week and will post the results once tested. Thanks again for the recommendation and advice. I really needed the help as I am not an electronics guy at all.
