Any suggestions on what can cheaply, and easily, be purchased to clean the eletrical contacts of motors? i have heard that WD40 can be used, but would like further advice on this.

Any ideas?

thanks

Keep WD40 away from motors !
Unmount the engines and clean them with excelerant. Not too long!
Typical 1 minute in a glass in both directions at a low voltage 3 a 4.
Remember to oil it again, with some thin oil.

Didn't try contact cleaner, eh? I use a precision parts cleaning spray but I think that's only available commercially. As Kai stated, re-oil the bearing surfaces after cleaning.

Hi Edo.
WD40 comes in a spraycan, and gets sprayed all over the car.
In some cases it makes the plasticchassis become sloppy, so the motor and bearing can pop-up. In all cases its makes a mess.
If you spray it in a cup, and then puts it in/on the motor i guess its ok, have never tried.
Use thin oil to oil the motor (put an amp.meter on the motor when you run it at 3V, look at the difference when you use different kinds of oil, and watch the difference in A).
Excelerant, hard to translate.
In Danish its called Rense Benzin, a direct translation is Cleaned Gasoline, does that ring any bells ?
Its that chemical you can use for removing Contact-glue from surfaces.
Maybe its just called Benzine or Benzene ?

You can get WD-40 in gallon jugs too, err, non aerosol form
The problem with it is that it makes a mess. It evaporates but it still makes a mess. It can also soften brushes so the motor might run faster for a bit if the brushes weren't seated in to begin with. However, the now soft brushes wear out fairly quickly.

Check out your local hobby shop and get a can of motor cleaner used for r/c cars. Works great and brings back the performance of a new motor. Make sure it says "safe on all plastics" on the can, which almost all different brands do.

Paul, Servisol (from Maplins) used to be a firm favourite at Maidenhead with the open SCX cans - you could give a quick squirt before a race and guarantee a two to three lap performance boost; nitrous for 1:32!

WD-40 is great for cleaning out gunked-up old motors - never would have thought of spraying this on a motor already in the car! It's also good for all kinds of general vintage chassis cleaning purposes.

For a contact cleaner, I just use something called "Speed Drops" from one of the major modern slot car manufacturers - excellent stuff. Not sure how this compares to the R/C cleaner, but imagine it's all related...

I wonder if the Excelerent isn't similar to what we call "Essence C" in France, used as a general cleaner of cars and wood tracks - pretty much just lighter fluid in US speak! (unless one of your chemists out there wants to give us a short course in the differences).

Hi Paul W.

Here one of the best motor cleaners out here (Pure Performance) motorspray. Its made for slotcar motors and also R/C motors (motors ONLY!) that's arm's , mag's etc. Go to (www.taeindustries.com) or your local raceway for it.
And if you want a all round cleaner that will not harm your bodys or paint jobs. Try (Primeracing's) armature ,body, comm, cleaner. Go to (www.primeracer.com) hope this helps you out. PS. A lot of the R/C motor spray will (SOMETIMES) work as well?

Don't use WD40 or any oil-based product as it will leave a residue that will only harbour more dirt and junk. Look at Maplin Electronics for a host of non-residue electrical cleaners that will not degrade plastic or epoxy bits in your motor.

I just lightly wipe with a cotton bud lighter fuel myself.
