Comet is a powdered cleaning product sold in North America and distributed in the United States by Prestige Brands. Scratch Free Comet with Bleach Disinfectant Cleanser contains 1.2% sodium dichloro-s-triazinetrione dihydrate (a derivative of cyanuric acid) and 98.8% 'other' ingredients. The only clues about the other ingredients in the product are disclaimers on the label that mention that the surfactants in the product are biodegradable and that it contains no phosphate. Despite being labeled as scratch free, its label also advises the use of plenty of water on delicate surfaces. Comet is not recommended for use on silver, painted surfaces, walls, soft plastic, aluminum and rubber. Mixing Comet with other cleaners, specifically dish soap, toilet bowl cleaners and products that contain ammonia, is dangerous.
