Storage Hazards

---snip--- Pinball machines often have this problem. Cleaning with just soap and water is not enough. Most current day batteries use an alkaline electrolyte. This will continue to do damage unless neutralized. On boards for pinball machine, using vinegar seems to do the trick. We first soak the board in a bath of 50% white distilled vinegar for several hours and then use a stiff brush to remove as much of the corrosion deposits as one can. Do note that you may need to remove things like dip switches, relays and keypad covers ( think in terms of where water can hide ). Also, any socket that is even slightly suspect will need to be replaced. After the soak, use a water hose and spray rinse the board well. Shake of excess water and rinse again. Dry quickly in a warm place. I often set them in the sun but for winter drying, an oven set to about 140-150F works well. Use a cookie pan or piece of foil to block direct heat radiation ovens. Also don't even think of using a microwave! ). Any trace that is rotted through will need to be replaced. Dwight
