Eco Cloths are made from a blend of polyester and polyamide. Polyester is great for absorbing grease and oil, while Polyamide is brilliant at absorbing water. They are made with fibres that are 100 times finer than a human hair which pick up dirt at the micro level ! When dry, Eco Cloths use electro-static energy to attract dirt like a magnet. When wet, Eco Cloths use capillary vacuum power to attract and hold dirt that is mixed with water. Bestselling cloth that leaves a streak free finish on any shiny surface.
