I got an EM pinball machine where the previous owner hosed it down with contact cleaner. There is now a goo between the contacts of a majority of the switches. What would be the best way to try and clean them before using a flexstone? I thought about spraying it with alcohol and blowing it out with an air compressor. Anybody have to deal with this before? I did a search but didn't find anything.
