If you spray any fluid on a R/C car, you take a chance of having problems. One must take extreme care to keep any kind of fluid away from the servos and receiver. I fried a $125.00 steering servo by getting fluid on the output shaft, it seeped into the case and went poof when I plugged the battery into the receiver. It melted a nice little hole in the bottom of the servo case and emitted a foul smelling smoke. I use 92% alcohol and plain old soap and water to clean my high dollar custom sprint cars. I then use a compressor to blow off the moisture. Dry graphite power (in the squeeze tube) works well on CVD joints and does not attract dirt. As far as after-run oils go, you can buy Marvel Mystery oil for $4.00 a gallon at the auto parts store. It will do the same as hobby shop after-run oil. Some nitro fuels on the market are adding an additive to their fuels that serve as after-run oils. I use Sidewinder fuel and have not had any build up of gunk in my engines. Sidewinder adds this additive to their fuels. After-run oil down the carb is not a good idea in that it does react to the rubber o-rings. They tend to break down and get soft over time after contact with the oil. Good old common sense goes along way with R/C maintanence. My 2 cents worth.

i take the engine an electronics off my maxx brfore cleaning it. i usually get a hose, and the pressure nozle, and blast the dirt off and away! i then spay it down with wd40, on the metal parts, so they dont rust.

May the schwartz be with you...

Fritz, you are correct. This is what I found:

I am in the glass business and we used to use WD-40 to lubricate the wheels on sliding glass doors, but they started to rust and pick up dirt so we switched to this stuff called PB Blaster.....problem solved.
    Your wheels rusted because the WD40 is a water displacer first It is not really a lubricant or a rust inhibitor although it does do a bit of both. If you need a lubricant and rust inhibitor there are much better products, as you found out with the PB blaster.

    Default cleaning

    Denatured alcohol works the best for cleaning and it doesn't kill bearings, like simple green does.

    IF u r willing to, i say use WD-40 to srpay and lubercate your shocks and springs and ur bearing. Also, another good cleaner for any car is nitro/electri cleaners. Really good for the bearings. Cleaing off dirt is easier with compressed air from a can or from an air comressor if u hav one.
