Sticky Coin Door

[HaRuMaN]

Yeah...   it seems as if the previous owner or user of the Mortal Kombat I now own spilled soda all over the control panel which then leaked into the coin door.  The problem is when adding coins, they get stuck about 50% of time and you have to hit the coin reject button.

What's the best way to go about cleaning/lubricating the moving parts?  Anyone know what parts in particular I should concentrate on?

Get a couple bottles of rubbing alcohol and soak the mechs over night.  Shake them a little under the alcohol once and a while to loosen larger globs if there are any.  Let dry for 6 hours or so then put some 3 in 1 oil on all the points that look as though they pivot or rub.

If there's a bill validator or any other type of electonic components you may not want to do that though...

Are the coin chutes (a.k.a. mechs) plastic, metal, or metal/plastic? Cleaning methods vary from type.

The solid plastic tannish/brownish COINCO brand can be cleaned by throwing them in a sink full of hot, soapy water just like it says right on them. Rinse, shake off the water and blow dry. These types of coin chutes need no lubrication whatsoever.

The solid metal coin chutes should be completely disassembled for proper cleaning, but if taking these apart and loosing several critical adjustments scares you, then here is what you do. Spray liberally with common household cleaner like 409 or Mean Green. Scrub with a toothbrush. Now rinse with hot water. Next boil a pan full of water and drop the coin chute (complete) into it and let boil for 10 minutes. Carefully dump out the boiling water into the sink and let the coin chute cool off and blow it dry with a fan. The only part of a metal coin chute that should be lubricated is the hinge pin that the magnet gate pivots on when you swing it open. A couple of drops of light oil is good.

If you have metal/plastic chutes clean the same as if it was a solid plastic one but dry it off as fast as possible so the metal parts don't rust. The only lubrication these need are at the hinge pin. Again only a couple of drops of light oil are all that's needed.

NEVER EVER USE WD-40!

Yeah, these are just the standard quarter acceptor, no bill validators.  It's made by Coin Controls and it looks like it's both metal and plastic.  I think I'll try the sink full of hot soapy water method, and dry the metal parts as fast as possible.  Thanks.
