After every session, I use a soft paintbrush to brush it off, then used compressed air for the hard to reach places. It's also a good time to check for damages.
Cleaning it is nothing compared to cleaning a nitro truck after running it through mud and wet grass.

yeah...I imagine that...mud and wet...and nitro...LOL...

I use a air compressor, after I think there is sand and dirt in it...

big fat paintbrush is what I use also...
