Many public restrooms in shopping malls, office buildings, schools, clubhouses and residential estates are cleaned daily, yet unpleasant odours such as urine, drain and musty smells may still persist.

This odor can sometimes recur even with daily mopping because ordinary surface cleaning may not be able to thoroughly remove the odor molecules hidden in corners, crevices, and sources of pollution.<\/span><\/p>\n
