I would use cotton swab, dip it in 91% or stronger (no water) isopropanol, clean the board and the switches, and then try one coil to see if it does not dissolve what it souldn't, and then if it is OK, proceed with it. No soaking, just wiping with alcohol-wetted swabs.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
