Just removing dust will not keep your clock clean or smoothly working. As dust gets into your wind-up clock, the oil becomes a rough paste and causes ware. If the clock runs in this condition for a long time, you will have to shell out a fat amount for your clock repairs. You can not clean your clock at home as it does not just need cleaning up but it needs over hauling.
If the oil point contains a black or a green residue, your clock might need an over hauling. It might also need re-busing to get rid of this residue which is a mixture of old oil and brass powder. Unless you have tried it before, or have the skills for it, do not try to oil your clock your self as you can see only half the oiling points from the rear. And the clock needs to be partially dismantled.
