How the hell do you clean these things?

Clean the outside "radiator" with a garden hose.
The inside one with an air compressor.

take all the plastic bits off and spray it down with bleach and water then rinse

Doesn't matter if you left it out. the outside of the unit and inside are distinct separate units. Only thing that passes through are two hoses for the refrigerant and a shaft for the blower.

If you want to clean it garden hose like the first anon said. compressed air inside might blow some dust out but shouldn't do much if you've been keeping up on cleaning the filter.

The only thing dividing the outside and inside is a few pieces of styrofoam I can see through...

I always spray the inside of mine down with a mix of water and bleach. It kills the mold and removes the smell for at least a few months, but it'll still look nasty and stained, and the smell for me comes back because I live in such a humid environment. Inside stays dripping wet.

Only use compressed air. Water helps push debris into places that can dry in a way it can't be removed. Compressed air blows everything out.
