What is U-Clean?

U-Clean is designated as the surface cleaning detergent for application of photocatalytic ARC-FLASH. U-Clean is a highly safe and effective detergent developed jointly by the Washing System Research and a pharmaceutical company 18 years ago to clean catheters and dialyzers. It is a new type of detergent that removes stains more effectively than conventional detergents. U-Clean generates oxygen when dissolved in water, and it cleans materials to be coated with the disinfecting photocatalyst.

A detergent for medical use must fulfill various conditions related to environmental hygiene and wastewater treatment. It must be phosphorus-free, extremely non-toxic and have high sterilization, bleaching, microbe decomposition, deodorization and antibacterial effects. U-Clean satisfies all these conditions. The details are as follows:
