So you are waiting on your parts or your playfield if you sent
it out, it’s a good time to clean and rebuild everything.
I start with the wiring harness. Even on new games the wiring
harness gets very dirty and will need to be cleaned. I remove
all of the bulbs and throw them away. I take the wiring harness
to the utility room and spray it with a degreaser. Bleche White
and White Lightening are my two favorites. Let the degreaser
soak in for a couple of minutes then rinse the harness with
very hot water. Turn the harness over and repeat the process.
I use a brush on some parts and generally agitate the whole
You can also put the harness into a tub, fill it with very hot
water to cover, and use Dawn dish soap. Let the harness soak
in the tub for a couple of minutes and agitate it to help get
the dirt out. With either process make sure you rinse the harness
thoroughly many times. You don’t want any residual cleaning
solution left on any of the parts. Once I’m done I take
the harness and hang it next to the furnace in the winter or
hang it outside in the summer. It usually doesn’t take
long to completely dry it.
