Trial #0
To evaluate effectiveness of the provided cleaners in regards to removing supplied gel and oils from stainless steel.
Three pre-weighed stainless-steel coupons were coated with each soil using a swab and allowed to air dry (68 F) for 24 hours. Dirty weights were recorded before immersing coupons into the provided cleaners provided by the company at room temperature (68 F) for two minutes. Coupons were rinsed in a de-ionized water bath for one minute and dried for 24 hours before recording the final weights.
SuperNova Extreme Detergent did not efficiently remove the supplied gel and oils from stainless steel coupons gravimetrically or visually. The contaminant, supplied gel, was clear, therefore there was no visual change in the cleaner as the substrates were immersing. While the substrates contaminated with Houghto-Draw 7060 were being immersed, SuperNova Extreme Detergent (1 oz/gal) visually changed cloudy showing an indication of some contaminant removal. While the substrates contaminated with Mobil SHC 634 were being immersed in SuperNova Extreme Detergent (1 oz/gal), the soil floated to the top of the cleaner. Once the coupons were rinsed and air dried, there was still residue on the surfaces.
