OK another silly question............ how do you clean and maintain a brushless motor... took my fly boat the fairbounre in mid wales and was messing around on the beach. salt water and sand. not a good combination.................. now want to make sure it is clean and runs well........... any ideas please.......... will WD 40 kill it dead..........................

I dropped my quad in the sand twice today.
Motors were jam packed with sand.
Quick blast out with an air hose, and I was back in the air

I've also dropped one in the sea. Stripped the motors off the quad and dropped them in distilled water to remove the salt.
Left them to dry in some rice for a few days.
That was 3 years ago, and they still run perfectly.

I had some motors packed with wet mud due to a slight error of judgement.
I flushed them out with tap water then blew them out with air and warmed them a bit with a hot air gun.
