I certainly would not use it anywhere - I have seen far too many mechanisms "gunked" up with the stuff.

Typical of an outdated product from that source - I'd put it in the same category as WD40 & 3 in one.

AFAIR, this subject was covered some time ago.

Commutators and associated brushes should not be lubricated with anything whatsoever. They need to be as clean as possible both mechanically and chemically to get the best performance from any motor.

There is some very good advice regarding the cleaning of motors, particularly regarding the restoration of older motors, to be found in the 'Collectors Corner' section of this forum.

I did look up the website of the product's manufacturer. Electrolube, but they don't specifically mention that application although it is obviously very widely used for other electrical contact areas.

Hi - never ever lubricate commutators or brushes with anything!. The brushes are graphite and provide their own lubrication! All they need is careful cleaning - I simply use liquid lighter fuel, on a cloth or tissue, which evaporates quiuckly. Remember this is a flammable substance!!!!!!

nb I have never had a problem with powerlube providing it is used sparingly and only in the right places!

Thank you all for your comments and cautionary advice re commutators and the perils of oil. I am pleased to say that I have not actually taken anything to a commutator except a cotton bud and and whiff of lighter fuel.... I realize now that my main problem in this direction is that I have probably wasted £5. which truly shocks me.!!
