Trial Number 2

Trial Purpose:

To evaluate an all-purpose degreasing cleaner on the removal of baked-on oil from stainless steel coupons.

Date Run:

08/29/2019

Experiment Procedure:

Production Soil (200 ml Quench oil, 200 ml cutting oil) was prepared mixing for 20 minutes at room temperature (68˚F) using a magnetic stirrer. Approximately 100 mg of the soil was applied to a pre-weighed clean stainless-steel coupon on one side using a handheld swab. Production soil contaminated coupons were baked in an oven for 30 minutes at 105° C (220 ° F). Coupons cooled at room temperature (68˚F) before taking dirty weights.

Three coupons were immersed in an unheated, ready-to-use cleaner for 30 minutes. Coupons were rinsed in an unheated DI water bath for 20 minutes before drying in the oven at 105° C for 30 minutes. Coupons cooled to room temperature (68˚F) before final weights were recorded.
