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.
F9 Double Eagle is BLEACH STABLE and works very well in your house wash mix.
