This will make the concrete absolutely “POP”, remove tire marks, soils and grime in the process. It is used when topical oil stains have been pre cleaned and the stains are actually at or beneath the surface of the concrete. When using this maintenance cleaner, your customers will be telling you that they have never seen their concrete so clean… and this clean will last longer than when using ANY and I mean ANY high pH cleaner. Concrete cleaned with F9 Groundskeeper will stay cleaner longer and be easier to clean the next time around. From my personal experience and from what other contractors who have been using F9 Groundskeeper are reporting, after cleaning the same concrete 2-3x with F9 Groundskeeper, the time spent cleaning the same contracts have been reduced by 25-40%. This is Big! Time is money! Typical dilution for F9 GK is never less than 10:1. Normal dilution is 10:1 to 15:1.

Causes severe skin burns and eye damage
Harmful if swallowed
May cause respiratory irritation
May cause drowsiness or dizziness

Surface must be free of topical, standing oils. Pre-clean standing oils (oils not in the pores and are above the concrete) with 5:1 F9 Double Eagle.

Wet Concrete so it is damp and not puddling. Spray on at 10:1 to 20:1. Agitate bad oils stains/bad areas if needed. Dwell a minimum 2 minutes and surface clean. Hot water preferred, cold water ok.
