De-liming
De-liming
Minerals accumulate on the interior surfaces of the glasswasher. The removal of lime deposits is called
de-liming and the glasswasher should be de-limed regularly. Inspect the machine interior for lime
deposits. If de-liming is required, a de-liming agent should be used in accordance with the chemical
supplier's instructions.
DANGER:
Death or serious injury may result when de-liming solution is mixed with sodium hypochlorite
sanitizing agent. Mixing may cause hazardous gases to form. De-liming solution and other acids
must never be mixed with chlorine, iodine, bromine, or fluorine.
CAUTION:
Skin contact with de-liming solutions can cause severe irritation and possible chemical burns.
Always wear eye protection, rubber gloves and protective clothing when handling chemicals.
