Trial Purpose:
To evaluate supplied product for DCC-17 removal from stainless steel and aluminum surfaces following TURI’s cleaning method.
Date Run:
05/08/2017Experiment Procedure:
The following experimental procedure is in accordance with TURI’s cleaning standard operating procedure for kitchen soil removal.
Soiling Process:
A set of pre-weighed stainless steel and aluminum coupons were contaminated with 0.5 grams of DCC-17 soil using a handheld swab onto the center of the coupon’s surfaces. DCC-17 was made with the following ingredients: Vegetable Shortening 33%, Lard 33%, Vegetable Oil 33%, and Carbon lampblack 1%. After all the stainless steel and aluminum coupons were contaminated with DCC-17 soil, the coupons were allowed to sit overnight then re-weighed 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 and 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 cleaner Vi-Jon Economy Pot & Pan with the comparative cleaner Brady Pot & Pan through gravimetric and visual efficacy evaluations.
Comparative Analysis:
Vi-Jon Economy Pot & Pan and Brady Pot & Pa were similar in performance levels, with respective efficacy ratings of 79.04% and 77.51%. On aluminum coupons, Vi-Jon Economy Pot & Pan comparable to Brady Pot & Pan; with a respective efficacy of 86.53% as compared to 90.05%. 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.
