Trial Purpose:

To test the efficiency of Clorox Clean-Up Cleaner + Bleach in the removal of Hucker's Soil from several substrates

Date Run:

03/24/2021

Experiment Procedure:

Ceramic, plastic, and painted metal substrates were selected, 3 of each, and weights were recorded. Hucker's Soil (Creamy Peanut Butter, Salted Butter, Wheat gluten, Egg Yolk, Evaporated milk, DI water, Printer's ink with boiled linseed oil, India Ink, Saline Solution) was produced and applied to all 9 coupons, 3 of each substrate. The substrates were allowed to air dry for 2 hours before contaminated weights were recorded. Each substrate's 3 coupons were placed into the SLW machine. The substrates, as well as the SLW cleaning block with an attached cloth, were sprayed twice with the cleaning solution. The cleaning block was run across the substrates for 20 repetitions (simulating 20 wipes). Cleaned substrates were then left to air dry for 24 hours before cleaned weights were recorded.  Final weights were taken and the experiment was concluded.

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.

Conclusion:

Clorox Clean-Up Cleaner + Bleach was 93.5% effective in removing Hucker's soil from ceramic, 90% effective at removing Hucker's soil from plastic, and 93.2% effective at removing Hucker's soil from painted metal. Overall, Clorox Clean-Up Cleaner + Bleach was 92.2% effective at removing Hucker's soil from all substrates.
