Trial Number 0

Two cleaners were tested at room temperature (68ºF) to evaluate removal of Carnuba Wax on stainless steel coupons. Six pre-weighed coupons were coated with Carnuba Wax. Each coupon was baked in an oven at 200 ºF for ten minutes and cooled at 120 ºF for five minutes. Coupons were removed from the oven, cooled to room temperature, and weighed to determine amount of soil added. Three coupons were immersed in one of the solvents for five minutes in a beaker. The coupons were air dried for 15 minutes. There was no rinse. Once dry, final weights were measured and efficiency was calculated for each coupon cleaned.

Fluosolv CX and Fluosolv NC did not clean the Carnuba Wax efficiently, Fluosolv CX had better removal gravimetrically. The coupons did not visually show removal of the soil after immersing. While air drying the coupons, the residual wax dried and turned white.

Ecolink Fluosolv CX and Fluosolv NC did not efficiently remove Carnuba Wax on stainless steel at room temperature. The Ecolink Fluosolv CX cleaned with an efficiency of 41.29%. The Ecolink Fluosolv NC cleaned least efficiently with an efficiency of 24.36%.
