It is used to turn NaClO4 into KClO4 and NaCl (see Preparing perchlorates). it is also used to increase smoke density in very small amounts; mainly to potassium chlorate based smoke compositions.

Potassium chloride is sometimes used as a water softener salt, instead of NaCl (check the label). It can be bought at hardware stores and grocery stores.
