Onzow zerodust works amazingly well for me and as far as I can tell it doesn’t leave residue behind which is the main culprit. It will always be a problem unless you live in a cleanroom or heaven forbid use your table with a dust cover on. Not so sure about magic sponge. They are cellular and use melamine as the a cleaning abrasive. Unless you’re dropping the stylus straight down and back up I would use extreme caution. It might be viable solution but with the zerodust you can see easily what is being removed.
