chalk and microfiber

I've heard that microfiber cleaning cloths are used to clean chalkboards in schools. What's the best way to remove the dust from the cloths?

Whack them against something solid, then throw them into the washing machine with a load of clothes? <shrugs>

These microfibre cloths are useless in the classroom. What's wrong with the old wooden backed blackboard rubber-outer. They could hit a pupil on the ear at 20 yards and stop any games one was playing under the desk or any idle chat. How can a microfibre cloth do that, unless the teacher wrapped it around a golf ball ? Perhaps the teacher should take in to class a vacuum cleaner and a vacuum bag. Placing the cloth in the bag and using the accessories to suck out the air may remove any dust and keep the cloth in a small package overnight. If it doesn't work the teacher can remove any attachments and throw them at naughty children so it won't be an entirely wasted exercise. HTH
