PS1/2 cleaning a controller

[Gameking-4]

I want to clean one of my controllers of my ps2, because its really really disgusting.
its not a official one, but a wireless copy.

it's like someone rubbed molten butter on it, there's a thick layer of fat filth on it.

I already tried with boiling water & cleanser, but it didn't helped.

I'm thinking of taking it apart and putting the outside in the dish washer, suggestions?

Disassemble it, then clean the plastic with alcohol and a loincloth. Try that first, its more safe.
