Interior electronics covered in dust - help !

[rigger67]

So as part of the system I'm putting together for my gf I took a punt on a Denon amp on GumTree and spent the princely sum of £5 on a beast of an integrated.
The fella selling it said I could bring it back if it was knackered, it worked when he tested it a year ago but has subsequently been sat in his garage gathering (a staggering amount of) dust.

It powers up okay and I tried a pair of headphones in it to test the volume pot and it's all good.
I've removed the cover and run a hoover over the obvious bits, without touching anything .. and now comes the serious clean-up.
There's thick dust pretty much everywhere, in all the nooks and crannies.
I'm guessing I could use one of those fluffy camera/keyboard blower-brush things but does anyone else have any suggestions ?

a compressor and a blower :eyebrows: thats what i use, just dont lat the noozle get too close:eyebrows: and do it outside

if its welded on then your stuck with leaving it or you can wash and dry them but thats not for amateurs

Aerosol compressed air and half inch paintbrush.

(bit of switch cleaner probably wouldn't hurt either)

When I was working on the bench calibrating much more complex and expensive electronic kit than a HiFi amp - we used this stuff - https://www.maplin.co.uk/p/servisol-antistatic-foam-cleanser-400ml-jp18u

Safe to use and does a great job - just make sure the amp is totally dry before switching back on and don't be too vigorous with your brush.

I have become a little more brave these days and do things like wash (mains) electric motors in a sink of hot water and Ariel. In the past this would horrify me, and I would have said water and electrical stuff, absolutely not.

But with a cct board I would happily use a 1/2 inch paint brush and sparingly use water and detergent, the important thing being to remove all detergent by thorough rinsing after agitation of dirt in to suspension, and then dry thoroughly, use a hair dryer to both blow off the excess water and also to evaporate that which remains.

Water is not recognised for the powerful solvent it really is. You can alternatively plat safe and use the more expensive RS Computer Solvent which is a CFC cleaner designed for this purpose.
