An aerosol composition is made from the concentrate and 5 to 10 percent by weight of a propellent sufficent to provide aerosol discharge while maintaining an in-can solids of 45 to 60 percent by weight. The process of making the concentrate comprises first forming in place the soap moiety and serially adding the adjuvants and abrasive while maintaining a penetrometer reading of 350 to 450 mm. in ASTM D217.
