AboutFOUNDED IN 1930, CSL WATER QUALITY, INC., originally known as Carbon Solvents Laboratories, manufactured and marketed solvents, cleaners and degreasers for educational facilities and school systems. Our principle product, SLATEX, a blackboard cleaner and finisher, restored blackboards to their original condition.
