Wait. So, taking it through the car wash was a bad idea?Where can I get the proper fender blackface logos to put on my R100?

Are they all the same or do they have different screw holes?
Each logo design has unique hole locations.
How do I remove the grille off my amp?
Check the lower right corner of your amp, there should be a tab there pull that tab (with some authority) and the grill comes loose.
How can you clean the speaker?
Use it, the vibration will shake the dust off; or do you mean the cabinet.
What do I use?
A mild cleanser on the cabinet, a damp soapy cloth, Windex, 409, I've used all of those in the past for dirty cases and cabs.
Do they need a regular clean, does it need just a wipe down or something?
They need to be dusted as often as your abode demands dusting be done.
