PC modem cleaning
My PC modem is internally caked in dust and seems to be making more noise now and poor performance. I expect it's likely due to dust build up and lack of air circulation causing heat build up affecting performance. Any tips or opinions for cleaning? I have no intention of disassembling any component other than the outer case for access use. I also and under the impression touching any component or PCB is not a good idea due to finger prints / static and also static again for reasons for not using a hoover. I was thinking compressed air?

Opinions welcome. Thumbs Up $W33T $0U7H3RN $UG4R

Compressed air and a brush - small paint brush - is what I use to clean circuit boards and the insides of my PC. Also use the vacuum cleaner to catch the dust, otherwise it just heads back to where it came.

Static shouldn't be a bit issue, but I usually make sure I keep my hand earthed to the casing every now and again to discharge any possible static.

Cheers

Isopropyl alcohol is also very good for cleaning electrical components if a good old brush and compressed air doesn't get it clean. If you go through life with your head in the sand....all people will see is an ar5e!!

Treat every day as if it is your last....one day you will be right!!

When using vacuum or compressed air, do not point it directly at the cooling fans, they can break down because of excessive speeding. Cheers, Vincent

Airline to blow it out.

The machines we have at work (fruit machines, quiz machines, digital jukeboxes) all use PC towers, and the amount of crap that they suck in from a pub/club environment is unreal. used to be worse when people could smoke in them too.

Just blow it out and as said, use a soft brush for the more stubborn bits.

So a pressure washer and de-greaser is a no-no then? Whistle

Actually, back in the 80s when I was a service engineer for Tektronix, we used to wash the circuit boards down first then put them in a very slightly warm drying oven for 24hrs..Smile

I wouldn't recommend that now though...

I don't have an air compressor but I can get some aerosol cans instead though.. Thumbs Up

Mal - Funny you mention that I do have some of that too but small wipes a whole box full. Ideal before applying anything like adhesive stickers and so on too. Thumbs Up $W33T $0U7H3RN $UG4R
