best way to clean a jamma board

[SUPER_SSII_TURBO]

I have some jamma boards that could use a little tlc, what is the best way to clean them and de-gunk the boards.  what should I use,?  thanks so much

Are we talking just normal dust and dirt or sticky hard-to remove "gunk"

If it's just dust canned air can do wonders. I've not had any that needed more than this.

Suprisingly, one of the most favored methods for normal dust and dirt cleaning is to wash them in a dishwasher. Just make sure they dry completely before powering it back up.

If you choose the dishwasher solution, make sure to remove the chips before

Ive found that VCR head cleaner works well. They make critical parts cleaner in an aerosol can.

Dishwasher.  Without much soap.

PS: I have NEVER heard of needing to remove the chips.  Just DO NOT let the board sit there and dry on its own time. Immediately take it out and dry it out.

I can confirm that Darth Nuno's Space Invaders II is still working fine.....I'm not sure if the Xevious still has the original PCB or was mamed though....

Atari also suggests the wet method in "The Book" (http://arcarc.xmission.com/PDF_Arcade_Atari_Kee/Atari_TM-129_The_Book.pdf), see attached clip.

Even so, I've never used it. As Atari suggests, this is only needed if the PCB is REALLY very dirty, f.i. when it's covered with rests of drinks etc. If it's just dust (which it is most of the times), I only do the "canned air" trick.
