Trial Purpose: DIY test for all purpose cleaning with water rinsing Date Run: 05/06/09 Experiment Procedure: A “Do-it-yourself" home formulation was evaluated for performance on several substrates and a soil for all purpose cleaning. Rinsing was added to improve residue removal. Cleaning : Spray cleaner on the coupons 30 seconds of manual wiping using a Garnder Straight-line washability unit at room temperature. After cleaning, coupons were sprayed with water and wiped dry. Parts were analyzed using visual and gravimetric techniques.

Each of the substrates cleaned and rinsed during this trial were cleaned above 85% with only one surface needing longer cleaning time. The plastic surface required 60 cycles of cleaning as compared to 20 cycles for the other surfaces. In addition, the plastic coupon was improved with a longer rinse process. The ceramic surfaces also needed additional rinsing time to achieve the 85% effective level. |
