Advice - Cleaning Speaker drive units

[enrae8]

As per title - I have some speakers to sell but the drive units are dusty and it really shows in pics
All grateful enormously advices received helpfully

If they're paper cones just brush them, a large makeup brush should do. If they're plastic, wipe them gently with a damp soft cloth.
