1. A method of controlling the spray pattern of a sprayable liquid abrasives composition sprayed from a manual trigger sprayer, said method comprising the steps of: a. obtaining a liquid composition comprising: (i) from about 10 wt. % to about 25 wt. % calcium carbonate particles; (ii) from about 1 wt. % to about 10 wt. % of an anionic surfactant; (iii) from about 1 wt. % to about 5 wt. % of a nonionic surfactant; (iv) water; and (v) an amount sufficient of alkaline and/or acidic pH adjusting agent(s) to buffer the final composition to a pH of from about 10 to about 14; and b. adding from about 0.01 wt. % to about 0.20 wt. % of a polyethylene glycol having molecular weight of from about 8,000 to about 100,000 Daltons to produce a sprayable liquid abrasives composition having a controlled spray pattern.
