Trial Number 4

Trial Purpose:

To test the effectiveness of The Pink Stuff on stainless steel.

Date Run:


Experiment Procedure:

Six pre-weighed coupons, three of each substrate per cleaner, were soiled with one gram of oven soil (85.4% butter, 6.5% sugar, 4.3% deionized water, and 3.4% all-purpose white flour) distributed onto each coupon using a swab. Coupons were then placed inside an oven preheated to 450F and baked for 1 hour. Once baking was finished, the coupons were allowed to cool for 20 minutes. Dirty weights were recorded after the coupons cooled at room temperature (68° F). Three coupons of the same substrate were aligned into a Single Line Washing Unit (SLW) with Wypall X60 attached to the cleaning sled. The Wypall X60 reinforced wipe along with the coupons were all sprayed two times with water after a small amount of the cleaner was added to each coupon; then the coupons were allowed to soak for 30 seconds. Afterward, the SLW was activated, and the coupons were cleaned for 20 cycles following an additional 20 cycles where a new Wypall was placed on the sled and sprayed again twice with water. Cleaned coupons dried overnight at room temperature before the final weights were recorded.

Trial Results:

Both The Pink Stuff and Easy Off Fume Free Oven Cleaner had an effectiveness of 95% removal for stainless steel.
