cheddatom Posted June 10, 2014 Share Posted June 10, 2014 A while ago I bought a mixing desk 2nd hand. While it looked OK when I collected it, it soon became apparent someone had spilled some sort of oil on it Now, I don't think oil would damage many electronic components, but there are a couple of issues (two Auxilliaries don't work etc) which I'd like to troubleshoot. To do this I could do with cleaning up all of the dirt from inside the desk. So, what's the best way to get rid of gunk and grime from electronics?

CamdenRob Posted June 10, 2014 Share Posted June 10, 2014 Get one of these from maplins Mind you if it's oily sticky stuff you might need some sort of solvent, this is really just for blasting grime... works well on pedalboards too. Quote Link to comment Share on other sites More sharing options...

Horizontalste Posted June 10, 2014 Share Posted June 10, 2014 Servisol 20 maybe Quote Link to comment Share on other sites More sharing options...
flyfisher Posted June 10, 2014 Share Posted June 10, 2014 Er, PCB cleaner might be a good start: http://www.maplin.co.uk/p/maplin-pcb-cleaner-200ml-n64an Quote Link to comment Share on other sites More sharing options...

flyfisher Posted June 10, 2014 Share Posted June 10, 2014 Ha! What are the chances of that . . . To the exact minute as well Quote Link to comment Share on other sites More sharing options...
cheddatom Posted June 10, 2014 Author Share Posted June 10, 2014 I have some servisol, but I'm nervous about scraping components. So, I can use the servisol to free up the gunk a bit but then how would you physically remove it? A sponge? I realise this probably sounds stupid Quote Link to comment Share on other sites More sharing options...
KingBollock Posted June 10, 2014 Share Posted June 10, 2014 I use a toothbrush for the bad bits, but kitchen paper if it's not too bad. Quote Link to comment Share on other sites More sharing options...
cheddatom Posted June 11, 2014 Author Share Posted June 11, 2014 OK, thanks for the advice, I'll give it a go! Quote Link to comment Share on other sites More sharing options...
rmorris Posted June 11, 2014 Share Posted June 11, 2014 Toothbrush or similar to brush off the gunk. Could use the pcb cleaner etc. but I tend to avoid that if possible because it tends to be horrible caustic stuff to be around. I'd try Isopropyl Alcohol as it's benign ( except to rubber - of course don't drink it :-) and a good degreaser. I don't suppose you oould get the pcbsinto an Ultrasonic cleaning tank ? But that would be good. In general it's the mechanical bits that may be the problem - pots and switches. Take a look at the Caig DeOxit products - they really work well.

cheddatom Posted June 11, 2014 Author Share Posted June 11, 2014 Thanks rmorris! I'll give it a go with servisol and brushes for now, see how I get on Unfortunately my ultrasonic cleaning tank is only big enough for a 16 channel mixer, and this one is 24 Quote Link to comment Share on other sites More sharing options...
