Trial Purpose:
To evaluate supplied product for DCC-12 oven soil removal from stainless steel and aluminum surfaces following TURI’s all-purpose cleaning method.
Date Run:
05/09/2017Experiment Procedure:
The following experimental procedure is in accordance with TURI’s cleaning standard operating procedure for all-purpose cleaning substituting a partially aged DCC-12 soil.
Soiling Process:
A set of pre-weighed stainless steel and aluminum coupons were contaminated with 0.5 grams of DCC-12 soil using a handheld swab onto the center of the coupon’s surfaces. DCC-12 was made with the following ingredients: Butter 85.4%, Sugar 6.5%, Deionized Water 4.3%, and Flour 3.4%. The coupons were then aged in the oven at 450 oF for 25 minutes (normal aging time for DCC 12 is 2 hours). After the aging of the soil, the coupons were allowed to sit at room temperature to cool down for 20-30 minutes before reweighing again to determine the amount of contaminant added.
Cleaning Process:
Three soiled substrates were placed into a Gardner Straight Line Washability unit. Two Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with 1 spray of cleaning solutions. The cleaning solutions were diluted to the desired concentrations specified by the vendor and heated to a temperature of 110 oF. Each substrate was sprayed 1 time with the same cleaning solution. The solution was allowed to penetrate for 30 seconds. This was followed by cleaning in the SLW unit for 20 cycles (~33 seconds).
Efficacy Rating Process:
The substrates were left to dry at room temperature for an hour before weighing to determine the amount of contaminant removed.
Trial Results:
The objective of the experiment is to compare the efficacy of the sampled cleaners: Vi-Jon Premium Pot & Pan and Brady Premium Pot & Pan through gravimetric and visual efficacy evaluations.
Comparative Analysis:
The Vi-Jon Premium Pot & Pan was observed to have similar efficacy on the aluminum as the Brady Premium Pot & Pan, with respective ratings of 79.91% as compared to 80.71%. On aluminum coupons Vi-Jon Premium Pot & Pan was observed to have an efficacy that was closely comparable to Brady Premium Pot & Pan, with respective ratings of 81.04% as compared to 86.19%. Table pertaining to the amount of contaminant added and removed using a gravimetric scale by its respective cleaning agent to measure the efficacy of the cleaners.
