Mild soap on the faceplate, and electronics cleaner/lube spray on the inside. Sold by Amazon. I like the older Marantz products
Pics of said Marantz?
The writing on the face will be delicate so don't brute force it with IPA, chlorinated solvents, etc. Try gentle like castile soap. Use a artist's rubber eraser for marks or smudges.
For the insides, I assume Molykote 33, YM-102(sold as Toyota Body Grease W) or Super Lube grease could work. I found this: https://www.hifiengine.com/manual_library/marantz/sr820dc.shtml
You need to register but it looks like they have the service literature there.

What would you put grease on?
In general, aggressively cleaning an antique piece is discouraged. As nthatch said, the silk-screened writing is prone to come off. If it was owned by a smoker you may have a lot of smoke on the inside of the display glass. Usually it is not complicated to take off the front panel facade to clean that part.

Belonged to a smoker....
Mild dishsoap and a q-tip and soft brush will clean it up.
If it smells like smoke it will slowly dissipate. Compressed air will clean the PC.
Be careful with the silkscreen lettering as smoke has eaten away at it and the lettering will be easily be removed during cleaning.
I worked as a tech for a company that serviced Marantz (factory warranty service) in the 70s, 80s and 90s - ask me how I know how easy it is to wash of lettering on a smoker's unit

Put the face plate and buttons in hot water and natural dishwashing liquid for an hour. Rubbed the crud with my fingers and it came off easily. Looks brand new now.
Vacuumed the innards and cleaned with isopropyl alcohol. The switches don't work so I will need to get a contact cleaner for the next step.

For decades we used Nutrol and it worked great - today, for home cleaning of pots and switches, I use WD-40.
pots = potentiometers
Best stuff I ever used https://www.amazon.ca/gp/product/B0...29fdd73&pf_rd_r=ASARKHWEXG9NER6GYXT5
Seems to be on Amazon.ca but not .com
Did you try WD-40?
Good luck

Are you familiar with opening and cleaning controls?
If WD-40 or Nu-trol won't get them up and running you likely will have to replace the controls.
You can't "clean" broken & worn out
Good luck to you
