F9 Double Eagle degreaser is a really nice product for those hard-to-clean areas with heavy accumulation of grease and oils, such as on dumpster pads, gas station pads, drive-thrus, etc. Double Eagle will help make that job go faster without using hydroxide. It’s a great option for your difficult oily surfaces.
Don’t forget about the F9 Cookbook, which will help guide you as to how the different F9 products should be used and how they are interrelated.
F9 Double Eagle is a great degreaser and general cleaning product that offers an additional purpose of neutralizing acidic products like F9 Efflo and F9 BARC. When finished using F9 Efflo,you should follow up with 8:1 dilution of F9 Double Eagle. If there are oil stains in combination with battery acid stains, F9 Double Eagle will serve two purposes in the pre-cleaning process; It will clean the oil and concrete AND neutralize battery acid. After application of F9 DE, you will need to surface clean just like any other “degreaser”.
