A. Regretfully, once solidified, the phosphates in Alconox detergent powder have been hydrolyzed by exposure to water or humidity and then have re-condensed and hydrated to form a phosphate cement. It is certainly possible to scrape and pound to break it up in to chunks and release powder and use these chunks for general purpose cleaning. It is not recommended to use the chunks for critical cleaning. Once the phosphates have hydrolyzed, they are chemically different than the original chemical and will not perform all of the dispersing, chelating and sequestering functions as well as the original formula did.
