Isopropyl alcohol and Qtips. Just had a smoke leak that ruined a speaker on a fairly new MTH Premier engine. It appears that on some engines (I would check them all as I found two others in my fleet that had the same issue) the rubber "gasket" that seals the smoke fluid inlet to the shell of the engine is not centered allowing a hasty smoke fluid fill to leak inside to the electronics. I would reapply the alcohol and let it dry out well overnight. Try again in the morning. Worked for me
