Phoenix Gold Phorum

Hi,

I have recently bought a MS2125 TA and it has a filthy circuit board (and I have a MS1000 which can do with cleaning). I was looking at docs cleaning pics:

I wanted to ask doc, what did you use to clean the MS2250? I just don't want to damage the amps.

Thank You

Hi,

I have done a search on this and didn't find much and since doc cleaned a MS2250as shown in the pics, I just want advise on how I can achieve similar results,

Thank You

I start with mineral spirits using a Q-tip. If that won’t break it up, I switch to lacquer thinner. Word of warning though, if you don’t get rid of every little spec of crud, the lacquer thinner will leave a discolored residue and it is even harder to get rid of. Lacquer thinner is only a last resort.

On the amp you linked to, I used Zap bathroom cleaner. Zap is corrosive and will destroy your board or parts if you leave it on there a long time. I take a Q-tip, slightly wet it with the Zap and start out in an open area and work it in. Try to stay away from the parts if you can. Zap eats all the junk off the boards and leaves the gold alone, assuming you don’t let the Zap sit on there forever in a puddle.

Did you buy my MS1000TA? I forgot who did.

LOL, When I was young I worked as an apt maintenance man. I used zap when nothing else would work to remove tub stains.

Anyways... Why not just PCB cleaner or isopropanol( sp) ?

PCB cleaner would probably work well. I have never heard of such a product. Do you have any links to what you are referring to, I might give it a try?

Yes Eric I bought the MS1000 of you (and i have taken tremondous care of it). Also once you apply the zap with the q-tip, how do you remove these from the board completely, is it with water or do you just rub them off with the cloth?

I would take some pics of the dust on the board later on and post them to ask if all the marks in the pic can be removed.

Thanks,
Haz

Keep rubbing with the Q-tip, or another clean Q-tip until the cleaner goes away.

C&G electronics near me sell some foaming spray stuff. Ive used it on some smoke covered motherboards and neaver had an issue. I dont know the name of it though...

Isopropanol is nice too. It wipes up easy and dries quick. Gotta be careful on plastices because of the heat thing though.

EDIT , isopropyl. I dont knwo why the hell I was thinking isopropanol.

How do you apply the PCB Cleaner or the isopropy? Do you spray it and wipe it of with a cloth till it goes away ? (I just don't want to damage the amps)
