The best thing I've found to clean face plates and knobs on these is a paste of baking soda and water. Just rub it on with your fingers or old toothbrush. It takes off the brown gunk, doesn't affect the lettering and leaves it like new. Obviously this means taking the knobs and face plate completely off and then rinsing well. Simple Green will corrode aluminum.
Didn’t know that about Simple Green. Since this appeared to be some type of clear coat ‘overspray’ acetone was the only thing that would even touch it.
Always nice to see the SX-x50 series get much needed love for another life of music. I have found a Dollar General cleaner called "Totally Awesome" has done a great job for me over the years...aluminum friendly as well. Thank you for your time!
Greetings from Cedar Rapids! The x50 series Pioneers are my favorites from that era. I just did a partial restoration on my 950. So glad you were able to get that one looking much better! I never would have even thought to try acetone.
Having restored numerous SX units, these products all work extremely well: windex with vinegar, Flitz polish, and Blue Magic polish. 99% Isopropyl can also be useful if used carefully. Be extra careful if using any sort of abrasive polish or anything like magic eraser or ultra fine steelwool. Soft cloths, artist brushes and foam pad brushes all work great.
@@millervintagehifi3034 I've used the baking soda paste on many receivers with no issues. The acetone did make sense given that situation. I'm wondering if alcohol or lacquer thinner would have worked (obviously test first).
@@millervintagehifi3034 Well known brands like e.g 3M have them in more than one graduations from high cut to the superfine polished finish The one, last in line which is less agrresive maybe could do the trick. For sure I'm happy with your final result. Congrats and waiting to see the interior stuff !!

I'm just glad I didn't mess it up :)
Looks great... much better than when you started.
Thanks! Overall it turned out well...stay tuned to see how it turns out :)

Aluminum mag wheel cleaner works good on the Pioneer SX receivers
I've never considered using it. I'll have to give it a try.
What about the Mr Clean scrubbers for something like that
That’s what I tried…I call them magic erasers.
Hi, do you think that polish cream for car paints or metal applied with caution would have any better result on the faceplate ?
That might damage the silk screened lettering.
That stuff is pretty abrasive, so I didn’t try it.

When you see a resin or a residue like that, and it's a 70s receiver, don't you usually assume nicotine?
I do, and if it is it comes right off. This was hard like a varnish.
