I never tried the dishwasher trick but I've been using Lestoil for years. Soak the board in full strength Lestoil for a few minutes and brush it with a paint brush to loosen whatever. Then spray with hot water to rinse the Lestoil and dirt off. We used a compressed air/water sprayer at the Navy Yard restoration shop. I use the kitchen sink spray hose in my shop. Dry well with compressed air or whatever you have. I've cleaned the old band switch type tuners, boards, chassis with IF transformers, and remote controls this way with good results. Some ICs may get water under them that takes heat or just sitting to dry for a few days, but that is rare.
