To evaluate products at a longer cleaning time.
Five products were selected based on test results from the previous trial. Each product was diluted with DI water to vendor suggested concentration. The products were then heated to 130 F on a hot plate.
The pre-contaminated stainless steel coupons were cleaned three coupons per product for another 15 minutes (30 total) using stir bar agitation. Cleaning was followed by a 15 second rinse in a tap water bath at 120 F and air blow off for 30 seconds at room temperature. Once dry, coupons were weighed a third time and efficiencies were calculated for each product tested.
Three of the products removed over 70% of the oil/starch mix after 30 minutes of total cleaning time. The table below lists the amount of soil added, the amount remaining and the percent removed for each coupon cleaned.
|Cleaner||Initial wt||Final wt||% Removed|
|SC Oven & Grill||0.0383||0.0427||-11.49|
|VPW SC 1000||0.0799||0.0303||62.08|
