F9 Groundskeeper is designed for situations where there is no thick grease or oil buildup, but there are stains – like oil, dirt, tire marks, light rust, etc. – just below the surface. Groundskeeper pulls out caustics in the surface and subsurface levels, brings the surface pH back to where it’s closer to neutral,and makes the concrete whiter. It also makes concrete more hydrophobic, which makes it less likely to stain and easier to clean. Groundskeeper is designed for maintenance of industrial-strength concrete. It is not for residential.
F9 Double Eagle is created for cleaning thick oil and grease that are on top of the concrete surface. Double Eagle is a double purpose cleaner/degreaser and neutralizer. It’s excellent for removing
thick oils/grease as well as for concrete maintenance. It’s also used to neutralize low pH products, such as F9 Efflo.
For maintenance accounts where you want to make concrete really
shine and look cleaner longer, you can pre-treat with Double Eagle. This will clean off oils down to the surface. Once rinsed off, add F9 Groundskeeper, allow to dwell for 2-5 minutes, then rinse off with hot or cold water.
