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?

Maplins PCB cleaner:

Just don't get it in your eyes, it's not nice.

Edit: Yeah, what Flyfisher said.

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 :)

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.

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 :)
