Conclusions It was demonstrated that the average soil removal values for the four 10‐minute wash Launderometer method could probably be essentially duplicated by a single 3‐minute Terg‐O‐Tometer wash and one 2‐minute rinse. The 3‐minute Terg‐O‐Tometer method did not result in the same comparative rating of four detergents, but a series of tests with several other detergents using a 5‐minute wash and a 5‐minute rinse (using for comparison purposes a standard detergent) resulted in quite effective ratings. Of 13 detergents tested over a period of time, the two test methods provided soil removal values identical within a 95% confidence limit. These data indicate that a satisfactory technique can be developed using the Terg‐O‐Tometer, which would provide soil removal values and ratings of detergents closely paralleling the results obtained by the Launderometer multiple‐wash method.
