    I've come to learn juat lately that 20% coupon doesn't cover a lot of items. Anything that says Central Machinery is one of them. Got to read the fine print. It's a bummer and I have less and less reason to shop there. Except for some odd little item now and again. Their tool sets are as much as Craftsman and other well known brands. Not that I want their tools. Please.

    Electronic manufacturers of any type would NEVER use water and soap.
    Water encourages corrosion and not all components are water tight.
    They use solvents of different types.
    Use compresses air, a small vacumn device, and a brush with non-static producing bristles.
    For a solvent - you can buy cans of different specialty types in stores or online
    but isopropyl alcohol wowks fine for most things.
    Use high % alcohol. Drugstore 70% has too much water, use 90%, ot buy special 98% from an electronics store.

    The thing is though at least some of us have bought electronic equipment at outdoor flea markets. When the weather wasn't so hot. When it eas pouring down. When that vintage item you've been waiting for is located at the wrong end of the tarp. The end that's a functional rain gutter, and is directing all runoff on and through the item. You brought it home anyway, dried it out thoroughly and watched it power up. So I'm not afraid of water anymore. It may not be the ideal method but it doesn't seem to be the worst.

    Your point is moot. We are not talking about manufacturing. We are talking about cleaning. And dishwasher detergents/agents contain corrosives. That point has been brought up many times already.
    We are talking about cleaning Filthy boards.. Not dusty boards. Gross boards with mouse droppings and urine accumulation. Mud and debris from flood damage. Extreme cases. The dishwasher works miracles in some of these situations.
    I have washed and repaired boards that any sane person would have said "its ruined! Its garbage, Throw it away!"

    These are some of my favorite clips for how to clean boards.

    Us folks in the vintage sythesizer hobby have to do this all the time.

    I usually clean all my motherboards by hand in a 2 part process. First off I remove all loose dust with a dry paintbrush, then I use a old toothbrush, fingernail brush, or something similar to brush with acetone or strong isopropyl alcohol. I even do this with badly dirtied boards because I"m a tad OCD about trying to make my stuff look as OEM new as possible. After all that's done I blot and fine clean using Q-tips and paper towels. Works well enough for me, even my desktops when cleaned off after years of running and getting covered in dust look brand spankin' new when I clean them off.

    Granted, I've never seen any "Found in a creek/riverbed" bad stuff in a long, long time.
