Please help me clean switches on my lovely Nak CA-5

So I use this slim line lovely as a phono stage. Some of the switches are a little bit fuzzy when turned (when I use it in pre amp stage obviously). So I got me Servisol Super 10, but I can't see an obvious place to spray it. Hopefully these pics will help someone explain to me. Ta.

If it's PCB Mounted, you're gonna have to take them off or spray where you can and hope some gets in!!!!!

the Alps pots I own have two small holes in the side of the casing - squirt in there (aided by the thin plastic tube you got with the Servisol?)

Failing that, squirt where the knob shaft goes into the barrel. Doesn't take much - just a brief burst.
