Protect your investment! As time goes on, the hard water spots can destroy the beauty of the glass causing permanent damage. The surface may be perfectly clean, but this damage is seen as a white, fuzzy or frosted appearance. This is known as corrosion and the alternative, in most cases, is the substitution of glass. However, on the glass surfaces treated with eko glass (DFI) ®, this damage can be avoided. The secret is found on the patented Diamon - Fusion ® technology that improves and protects the surfaces treated with an ultra thin barrier, against: • Mineral deposits from hard water • Environmental pollutants • Erosion
