Hi,

Earlier today, I got my new MVS4 PCB. It's quite dirty and I cleaned some parts using a napkin, nevertheless I don't feel that's the best method, specially where the ICs are located. What's the best method/product to clean the whole PCB without damaging anything?

Also, what was supposed to go here?

Thanks!
 
For layers of dust like that I use an extra soft toothbrush and compressed air. Usually does the trick. If there are small problem areas I use a qtip and alcohol to touch up.
 
That's pretty dirty. If it were mine, I'd scrub it down with degreaser using a toothbrush. Rinse thoroughly and let it dry for a few days in front of a fan.

Nothing went in that unpopulated spot on the PCB.
 
Simple Green works wonders with SmokeMonster's plan.
 
I wash all of my super dirty boards with simple green and anti static scrub brush, rinse, compressed air to get all excess water out and then dry it in the oven for 1-2hrs. I havent had a board fail because of this yet.
 
clorox wipes + tooth brush + compressed air...

I've also done the dishwasher method but let that dry for 2 days. I had a NBA Jam that looked like it was buried underground and now its ultra clean.
 
Just make sure to remove any batteries before you use any wet methods. I killed a CPS2 B-board by accident this way. Won't even boot with decrypted roms.

Sorry for my poor English, but, for "rinse" do you mean to wash it with water? wouldn't this damage the capacitors?
 
I know that it sounds crazy to clean electronics using water, but if you are careful, it's a great way to clean dirty boards. Just remove socketed chips and batteries first.

And try to dry using compressed air if possible. Older pcbs tend to have components that can rust. This is not a problem with modern components.

I'll test it with an old double dragon first...
