SMOKE FLUID

No huge issues with the fluids usually other than the mess as ling as you are using the big name brands.

It likely spilled onto something else kinda hot.

You can spray things clean withCRC electronic (found "anywhere") contact cleaner (minding paints) or mop up other ways. Maybe let gravity do some drip work, etc.

Wiping board edges well is a good idea in case edges aren't sealed type or edge was missed, etc. (that might effect laminated board long term cohesiveness.. would likely stll work though.)

It's nearly like mineral oil, or baby oil, fairly neutral.

Thank You!!!

It has been reported that smoke fluid on the Lionel RCMC has killed the board.  I hasten to add that I always suspected that it was something else that kills them, not sure how some mineral oil should kill the board, but that's what Lionel has stated more than once.

Yes. I remember that about when the Vision Big Boy came out and there were some issues. I put my Fluke meter probes into a pool of smoke fluid and the reading was absolutely infinite ohms. Just to check. I've done that with laboratory grade distilled water and gotten about 10 megohms. So not even that much conductivity.

I think Lionel was quick to blame the customer for their failed boards. Not uncommon with companies.

I always had my suspicions, but I figured I'd let it ride.  I know I've taken many oil soaked PCB's out and scrubbed then down with Alcohol and put them back in service.

DETROIT, you may have just created a bubble in the smoke unit's stack hole. You will get the same results when a bubble is formed after adding fluid. I keep a small Sip Ups straw handy to stick down the stack and blow air down in order to pop the bubble.
