Having worked as restaurant manager for a couple of years now, just wanted to bring up some safety issues.
This Apex line is a new generation of detergents, designed with more additives than the regular stuff. That being said, the main ingredient is the usual; in this case, potassium hydroxide. Caustic, nasty stuff. Had two workers comp- involved situations where porters had severe damage to there hands. One stuck their hand in a clogged dispenser, instead of calling me over. Another was changing out an empty container (previous generation detergent came in a plastic casing), and a leftover piece landed on his arm.
No matter what it is, take all possible safety precautions to avoid an issue, including heavy duty gloves and googles, if you plan on hammering it into pieces. Products as caustic as this can melt your skin away in seconds.
