I made an accidental discovery when dusting my lab equipment with the Swifter brand cleaning cloths. They work great as advertised picking up and holding a surprising amount of dust rather than redistributing it. I am cheap and decided that one cloth was not quite used enough and set it on the bench for later. A few days later when I picked up the cloth, it released a cloud of dust. I had never connected the action of rubbing the cloth while dusting to why the cloth has an electrostatic hold on the dust. Obvious in retrospect.
