- Example 4 Removal of Polymerized Soil Composition C (the concentrate) was diluted with tap water to 1 wt.% of the concentrate. Steel coupons coated with heat-polymerized corn oil were placed in the solution overnight. By morning, the polymerized oil on the wetted area had fallen off the coupon. Compositions containing 0.1 wt.% of the individual components of Composition C, did not affect the coated coupons. This demonstrates the effectiveness of the composition of this invention as a potent hard surface cleaner without the need to resort to harsh chemicals such as sodium hydroxide.

- Composition C was diluted with tap water to provide 1 wt.% of the concentrate. Pouring the diluted material over a rusty steel step stool removed significant amounts of rust, demonstrating the effectiveness of the composition as a rust remover. Similar treatment of the rusted area with water alone gave no rust removal.
