A. Commercial bleach contains surfactant which is detergent besides chlorine. When the glassware is cleaned with Superge, no residue remains on the surface when it is dried. However, the surfactant of commercial bleach remains on the glass surface. On top of it, Superge can easily be washed off under running water, but commercial bleach leaves a “slimy” feeling and its detergent may easily go in the aquarium water. ADA glassware products such as Pollen Glass are designed for underwater use. Highly safe Superge is advised for the cleaning of such glassware.
