did you wait for all the metho vapors to evaporate and dissipate first, or did you power it up and have the coin door blow open and knock your knackers into next week again like you did with the contact cleaner that one time. 
seriously though, great tip, they look like they have come up like new. 
I will be doing this my self when it is needed.
Don't laugh... I hate to say this but if set that contact cleaner on fire TWICE now! I was under the house working on a 1959 ROCKET.. used the spray and had the PF up. Just as my wife pulled into the driveway, for some reason, I hit the START button... click...click.. and then WOOF! Big ball of flame came out of the cabinet and up to the ceiling.
My wife came in shouting " What the f*ck are you doing" as I was busy jumping around on the schematic that was on fire.
I don't use contact cleaner anymore...
