That's what you're supposed to do!

I spray my motor after every run no matter what. For a deep clean, I occationally, take a tooth brush and simple green and scrub the cr@p out of it....then motor spray.

mafiaracers - Yep, I use simple green too, works great and is cheaper then buying motor spray all the time. I usually drench it in simple green then rinse really well with water and repeat, then I hit it with a hair dryer. The only problem is it can take the print off the tags on stock arms if your not careful.

Yeah i use buggy blast and have had great results being its in a compressed can it comes out with resonable force to blast the dirt away.

I usally cut my motor every 3 to 6 run for it to stay fresh then I spray it down with hpi nitro blast, and replace the brushes.

While you have it apart its a good idea to:
shim the arm
change brushes
cut the comm
check/replace brush springs
clean/oil bearings
align brush hoods
physically clean the inside of the hoods with a comm stick or q tip a blast of cleaner wont remove buildup in there;
etc. for a fast and reliable motor

So can you actually drop your armature in Simple Green?

Yeah...it won't hurt it. But do that if you want to scrub your motor by hand.....otherwise dump your motor into a jar of motor spray and leave it in there until it all evaporates.

Lysol Basin Tub and Tile Cleaner works also.

Soap and water works just fine....just make sure its properly dried. I typically will use a hot air gun and then use my air compressor.....

While motor spray works ok, its not cheap...I would only use it like that at the track, but I would still find a compressor or some canned air to blow it off when I was done.

Simple Green can be used, but it will take out any markings on the armature or arm tags...rendering most stock motors illegal from a tech point of view. Lysol tile cleaner does work very good, but I find it overkill on arms....its what I use for cans and endbells though.

okay i blasted it with the motor blast and everything is okay, and i do all that stuff exept for align brush hoods and shim the arm (i just use the stock shims that came with the motor)
why is it important for brush hoods to be aligned? dont they do that at the manufactor, what causes them to become out of line?

They need to be aligned properly to conduct efficiently....if they are not, you will not only lose power, but you will generate additional heat into the motor.

Its not done very well at the manufactor......and there is quite a few reasons why you want to align them correctly.

You might visit www.rccars.com and check out big jims motor forum...you can get all the tips and tricks to aligning your brushhoods....just do a search and you will find it.
