I know folks disagree on this — and I would never power wash — but I always completely empty the cabinet, spray it thoroughly with a hose and then let either dry in the hot Texas sun or with fans if not sunny.

Meanwhile I also spray the bottom board and it’s contents off (usually avoid the transformer as I ca ) with a hose and then dry immediately and thoroughly, usually setting several fans toward the board for 24 hours after.

All comes out nice and clean and no issues whatsoever. Have done this on more than 20 Gotttlieb EMs.

ok I’ll try to take pics on this Jacks Open I’m about to clean up.

I hear ya. Don’t get me wrong, I’m never soaking the parts but I spray the bottom boards off (and the empty cabs of course), and when spraying the bottom boards there is a residual amount of water that gets on the parts on the bottom. It does clean them off a bit. I fan-dry immediately and thoroughly so have never had an issue.

Here’s a recent pic of the bottom board of the Top Card I just restored — nice and dust-free from a good hosing off.

Ok as promised here's a video of me cleaning the cabinet and bottom board by spraying off with the hose and then drying in the hot sun. I used a fan (as always) to help with the drying on the bottom board.

Photos of the nice dry cabinet and bottom board as well. I think I've restored 24 games over the past nearly six years and I've done this with more than half of those. I love having a clean cab and bottom-board to work from.
