Trial #1
To evaluate the efficacy of FB-1000 at various concentrations and temperatures compared to a 2% caustic cleaner in removing DCC17 grease soil from a variety of substrates.
A total of 27 coupons, three each of stainless steel, plastic, and ceramic per product solution, were tested using FB-1000 at 10%, 2%, and 1% dilutions, and Alpha Chemical's Veracity Caustic Cleaner (sodium hydroxide) at a 2% concentration. FB-1000 was tested at room temperature (68°F) and 120°F, while the comparative caustic cleaner was tested only at room temperature.
Initial coupon weights were recorded before contamination with DCC-17 (0.25g applied to each coupon using a handheld swab). After drying overnight, the contaminated "dirty" weights were recorded. Three coupons per substrate were cleaned in a Gardner Straight Line Washability (SLW) unit using a Kimberly-Clark Wypall towel and two sprays of cleaner (~2.5 mL per coupon) at the designated temperature. Cleaning involved 20 cycles (~30 seconds). Cleaned coupons were air-dried for 24 hours before final weights were recorded to quantify soil removal and evaluate cleaning efficacy.

FB-1000 at 1% and 2% dilutions demonstrated grease removal effectiveness comparable to the 10% solution. All three FB-1000 dilutions at room temperature performed as effectively as their heated counterparts.
FB-1000 at 10%, 2%, and 1% dilutions demonstrated grease removal effectiveness comparable to 2% Veracity Caustic Cleaner, both when heated and unheated, on stainless steel, plastic, and ceramic substrates.
