Keycap cleaning

[Ymac]

For the yearly maintenance, I want to clean my DK9008 Shine 3.

The keys are dirty and the board (It's a white board with black keycaps special edition) is dirty as well.

I think the stock keycaps are ABS UV coated, so I was advised to not use alcohol on them. can I just use tap water? dish washing soap maybe?

I don't want to damage the keys.

Advice will be appreciated.

 

btw, I have one faulty LED, mechanicalkeyboards.com want me to ship it to them for repair, but that would cost more than the damn thing worth, so what kind of LED do I need? like, size and exact brightness and color?

 

Thanks!
