These Blue Microfiber Cloths are more effective than a regular cloth for chemical spraying and dusting because they are highly absorbent, have positively charged fibres that attract negatively charged dust particles like a magnet, and can be used damp to increase absorbency and the fiber’s capacity to pick up dirt and residue. It can be used for a variety of tasks, including dusting, cleaning appliances, scrubbing bathrooms, and wiping down kitchen counters. Dimensions are 400x400mm (LxW). also offered in yellow.
