A good way to clean stuff off a magnet pole is adhesive tape.

If the surface is too convoluted for the tape to work, there is a
product in the UK called "Copydex", which is sold as a carpet glue but
can be used to remove debris from a magnet.  It is an emulsified latex
solution which doesn't stick well to metal surfaces and can be peeled
off easily.

You apply the Copydex thickly over the surface to be cleaned - and then
wait.  Eventually the milky white liquid dries to complete transparency,
then it is strong enough to be peeled off, bringing the debris with it.

Sounds like a modern equivalent to soft Collodion, which is widely
used to clean optical surfaces.
