F9 Groundskeeper
F9 GroundsKeeper (F9 GK) is a highly concentrated cleaner to use after your initial cleaning/degreasing. If existing oil and hydrocarbon stains are present, it is recommended to clean those stains with F9 Double Eagle Degreaser first. Once you can see the concrete pores below the stain then apply F9 GK to surface (at recommended dilution ratio) and surface clean. This will get the concrete set up for maintenance cleaning with F9 Groundskeeper.
