Subject: TECH: cleaning cloth insulation in very old games
Date: 1999/04/19
Question - I am looking for suggestions on how to clean the dirt and oil off the
cloth insulation in very old pinball machines. I am compulsive when it comes
to cleaning machines like to clean the insides as well as the visible parts.

Answer - This is not exactly the same, but I have had good luck with cleaning
cloth-covered wiring harnesses from some of my English cars and my jukebox in
the following manner. Note, this is for harnesses that are OUT of the
machine, and I can't imagine anyone wanting to take one out of a bingo --
*shudder* -- but maybe you can adapt this...
Anyway, this has worked for me on the type of wiring that is several or many
vinyl-insulated wires inside a braided or woven cloth covering. I just fill a
large dishpan with warm soapy water (dishwashing liquid is fine) and lay the
harness in it. Gently squeeze up and down the length of the bundle, maybe
changing the water/soap mixture if it gets particularly greasy or dirty. You
don't want to scrub and abrade the cloth, especially if it is old, but
squeezing seems to do no harm. When dirt and oil/grease are removed, change
to clear water for rinsing in the same manner, then set out in the sun to
dry.
