Ok I gave a copy of SSIV that I got from Yaton a bath with water and rubbing alcohol and this morning I went to check how dry it was and there was white powder like substance on the back of the boards and some what on the front. Did I cause corrosion or is it some residue from the rubbing alcohol since it was not denatured?

Did you use distilled water or tap water? If I were to guess, I would say it's probably calcium out of your tap water.

Ummmm isn't it really really really bad to submerge PCB's in liquid?

I always clean my boards with cuetips, rubbing alcohol and compressed air. Lemme know if you game ever works again after fully drying out.

I used tap water with Isopropyl. This morning I scrubed it back down with the brush I was using with Isopropyl on it. Hopefully this evening when I get home its dry agian but with out the white stuff. I was thinking maybe it had corroded but I thought it took a while to do that not over night. I may also pick up some contact cleaning from radio shack and give it a once over with that.

Isopropynol will leave white stains if used in conjunction with water... Just clean them off with pure Isopropynol, making sure there isnt any water left on the board.

Ahhh I see said the blind man. Thanks for the tip... I will keep that in mind and clean this stuff off and let the board keep drying.

what would be the reason for this? Did the cart not work? I would clean the case and the contacts...this seems unecessary.

Have you seen Yaton's really dirty stuff? It's like he stores the PCBs out of the cases, in a landfill, under about 3ft of feces (in a locked filing cabinet, in a disused lavatory, with a sign saying "beware the leopard").

They're horrible. Can't blame him for cleaning it at all.

Yes, I own many....I realize all this. But if the cart works and the dirty bits are covered. Why risk fuckin' up the cart?

I know...PCB's.

but boards hidden away inside carts seems excessive, that's all

Because you know it's under there. Taunting and mocking you.

So am I mistaken on this subject, can you submerse PCB's in water to clean them? As long as you don't power them on while still wet will they be fine? Some of my Yaton carts are just terrible, but I don't know if I would go to that length to clean the PCB. I always clean the connectors, and the shell, but never the PCB. I may spray it w/ some air, but thats all.

From what I hear some people even put PCBs in the dish washer.

Yeah every once in a while the cart would act goofy graphics glitches mainly. I opened the pcb when I first got it and could not belive the amount of filth I mean come on. It had some soda/dirt/toxic waste on it that I could not identify very dry powdery but devinatly odd. It did not disolve in the water by its self I had to add the Iso to even get it off and it took a littel scrubbing to clean it. I paid $25 for the cart I figured if I f'ed the cart no big deal but if it fixed the cart and made it work more reliably then even better.

I've been known to do this. I remove all batteries and socketed chips and throw them in the wash cycle with a drop of detergent. When it's finished, I blow it off with a compressor and leave it to sit in the sun for about an hour. Lemony fresh!

I've never had it fix a problem that probably wasn't fixed just by removing and re-installing the chips, but it sure makes looking for broken traces a lot easier. Plus on some of the sockets, you actually find out which ones are rusty vs. dirty so you can replace a potention problem. I have never "killed" a board by doing this.

I went ahead and picked up some electronics cleaner from Radio Shack. This should help with any issues I might have.

A toothbrush and a can of compressed air is easily the best way to clean carts.

Simply go over the boards with the toothbrush and then use the compressed air to get rid of any remaining dust.

My problem was not dust but some dry nasty substance water did not even budge it. I had to use the Iso to get it to brake down and then it was kind of slimy.

Well I got home last night cleaned a few spots with the electronics cleaner I got from Radio shack let it sit dry for a couple more hours then tested it. It appears to be fully functional I ran a CRC check using the UniBios and all was well. Game plays normal. The cool thing is the odd graphics issues I was having seem to be gone now so I am happy.

I bought a KOF'96 cart from Yaton, had a scrolling GFX issue so I cleaned the fuck out of it with a toothbrush and trusty ole water from the tap, dried with a hair dryer and bam, not a GFX issue in sight.

Cleaning PCB's with water is good.

The only time you have to be really careful with the toothbrush is with really old pcb's sometimes the green coating on top of the traces can bubble and if you scrape too hard you could easily tear the coating off and maybe break some traces as well. I have mainly seen this only on early '80s and earlier pcb's. I've never broken one of these traces but that bubble look makes me nervous about cleaning hard, so I stay very careful, traces are only thin strips of metal foil...

cheers,
