Generator Cleaning Question

[Tom Wesenberg]

I use compressed air and a syphon sprayer with gas. I prefer to use gas with NO ethanol.

I made some end plates to cap off the field coils while I sandblast the case.

I cannot get gas with no ethanol. Is there anything else which will not damage the field coils? How about brake cleaner or paint thinner?

I have used gas with 10% ethanol and blow dry it right away, and there has been no damage. It sure hurts the hands more than the good gas though.

I believe that Tom is saying to clean the outside of the generator only.. Do not clean the coils with solvent.

I've also cleaned the coils with my syphon sprayer and gas. I don't soak them, but a quick cleaning with the compressed air and gas will clean the junk off without hurting the coils. I stay back from the wrappings a bit with the compressed air. Sometimes I use gas and a soft paintbrush.

NAPA sells an electromotive cleaner in a spray can. But the books say not to use anything that will desolve the coating on the field coils. I was wondering how kerosene would work = much easier on your hands too. I don't care to use the more powerful cleaners.

He mentioned the coils also. I use Lectro Clean it is made for electric motors.
