what to use to clean Brushless motors

[royalcasa]

What is the best way to clean dust and prevent rust in the brushless motor.
Thanks.

Rust means your motor got in touch with water so you have to waterproof carefully your boat .Corrosion X is what I've been using for years.Gill

I am new to the hobby, looking to prevent future problems.

You should be able to find some? I guess I was lucky to find 2 cans of the original Corrosion Block at a LHS. Check for similar products from a Marine supply store in your area. Funny how a friend of mine was doing direct marketing for Corrosion Block about 10 years ago when it first came out in Canada and now it's un-obtanium?

Clean out with WD 40 let sit, check for brown rust from bearings, replace if required, spray it out again and then clean out with 99% isopropyl Alcohol and re-lube bearings

If you have let it sit after it got wet most likely there is a buildup of rust inside the motor on the stator plates that would require a complete dis-assemble of motor to use a toothbrush to get most of the brown rust off the inside.
