An excellent tip Steve, though with a minor caveat.

If you do use brake cleaner, then fine. Though it's best to do that in a
well ventilated place. Brake cleaner - last time I used some on my bike,
is Trichlorethane/Trichlorethylene (the original engineers "Trike").
It's vvv "vaporous" and one of the original "sniffers delight" type
materials (which, if memory serves me correctly, was one of the reasons
why it was banned in the engineering industry for use in large quantity
i.e. in cleaning tanks).
That said, it's a bloody marvellous solvent/cleaner for just about
anything oil based - some surfaces may show a white residue (similar to
that mentioned by whoever it was that was explaining the benefits of
"canned air" aerosol sprays), but that's usually removed from visible
places with a moist cloth.
