Trial Number 4

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.

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

Overall, both cleaners were effective at removing the baked food soil.
