Abstract
Abstract Hard surface acid cleaners providing fast acting and effective cleaning results across a wide variety of problematic cleaning areas, comprise alkyl aryl sulfonic acids and at least 50.0% by weight of water. Suitable alkyl aryl sulfonic acids are alkyl benzene sulfonic acids of the general structure wherein R is alkyl averaging 5 to 20 carbon atoms in length and wherein R and R. are H or alkyl averaging 5 to 20 carbon atoms; and when R, is alkyl, R 2 is H. Additionally, solvents, antimicrobial compounds, defoamers, thickeners and other cleaning adjuvants may be added to these hard surface acid cleaners.
