$\mathrm{C}{\mathrm{a}}^{2+}$and$\mathrm{M}{\mathrm{g}}^{2+}$ions form insoluble calcium and magnesium salts in the form of scum

$\mathrm{N}{\mathrm{a}}^{+}$and${\mathrm{K}}^{+}$present in soap react with$\mathrm{C}{\mathrm{a}}^{2+}$and$\mathrm{M}{\mathrm{g}}^{+}$and hinder cleansing process

a large amount of soap is to be used in presence of$\mathrm{C}{\mathrm{a}}^{+}$and$\mathrm{M}{\mathrm{g}}^{+}$

scum formed by combination of$\mathrm{N}{\mathrm{a}}^{+}$,$\mathrm{C}{\mathrm{a}}^{2+}$and$\mathrm{M}{\mathrm{g}}^{2+}$stick to the cloth and are not removed on agitation
