Hi,
I have unearthed a bunch of my old Dynaco and Marantz eqpt from my attic, garage, closets, etc. I am wondering if there is a way to "spray clean" a whole chassis, assembled, to get some of the dust and grime off without dissassembling the whole thing ? Perhaps some sort of MEK or acetone spray ? However I do not want to dissolve the lettering off the components etc. ANy suggestions ? THX.

I need the answer too.
However, both MEK and acetone are carcinogenic. MEK (methyl ethyl ketone) is a particularly powerful carcinogen. Acetone was banned as a nail polish remover because of its carcinogenic properties.
I've used some Formula 409 on a particularly nasty Pioneer SX-1250. On the transformer and metal parts, anyway. I've stayed away from the circuit boards and the front panel.
compressed air and a tooth brush will do it but takes awhile, deoxit works good in some places if its a tuner or receiver dont get any thing on the tuning capacitor.
I've carefully used Formula 409 too, as well as isopropyl alcohol. Oddly, it too was on an SX-1250. The pots and switches I'm still cleaning. By the way, three of the lamps were out, and I couldn't find replacements so I replaced them with orange LEDs and resistors. The Stereo light worked on a much higher voltage, and required a different resistor. The LEDs are working well so far. I'm glad they used DC for the lights.
I tried using a toothbrush, but it tasted terrible afterwards.
