Pro Tip
General Cleaning Instructions
Ensure the surface is free of topical, standing oils.
Pre-clean heavy oil buildup (not in pores) using F9 Double Eagle at 5:1.
Application
Wet surface so it is damp but not puddling.
Apply F9 Groundskeeper diluted 10:1 to 20:1.
Agitate stubborn oil stains or heavy buildup if needed.
Allow a minimum 2-minute dwell.
Surface clean and rinse.
(Hot water preferred; cold water acceptable.)
