How best to clean an Apple ][+ keyboard

Hi,

I'm trying to clean an Apple II+ keyboard. All the keys are working, but it's supper dusty under the keys and there are a few cobwebs. What's the best way to clean it?

Thanks!

Apple III - mouse dropping on motherboard !!! HELP

I got a A3 to restore. I pulled the motherboard out and it has a lot mouse pee and little pellets all though the center part of the board. No nest though.
How best to clean???

FYI - Problem with IIe

Continual CRs when booting IIe.

Super Serial Ethernet Card

Finally working...

More Disk ][ Troubles

Neither of my Disk ][ drives will read any disks. I've had this problem before; replacement of the 74LS125 on the analog card solved it then. I tried a similar thing today, but the problem persisted.

For what it's worth, I noticed that the impedances of Drive 2's head are higher than they should be according to Sams Computerfacts.

Monitors

The Apple III owner's guide includes a schematic but
the Apple Color Composite and Apple Color RGB do not.
Purposeful left out?
Does anyone know if there are schematics for these
monitors?

I have looked at

mirrors.apple2.org.za./ftp.apple.asimov/documentation/hardware/schematics/

and they are not there.

Apple II Plus No Video, No Beep, but Power Light On

I recently bought a working Apple II Plus from eBay and it worked great. However, a few hours later I pulled the top off while it was on, and the video signal cut out. I turned it off and back on again and now only the power light comes on. No beep on boot or video output. Several Apple repair manuals I have found give a list of a few chips that may cause this exact issue.

Advice requested for repairing disk image on CFFA3000

The disk image that my BBS runs on (Dura Europos) has developed errors. I fear they may be the result of adding the Fast Chip IIe and upgrading to GBBS Pro v2.14, though I hope that is just a coincidence.

I ran Mr Fixit, but it doesn't touch the errors. I want to replace the .po disk image with a clean one, but so far I have failed.

Here is what I tried:
