F9 Groundskeeper is a high performance maintenance cleaner to use after your initial degreasing, pre-cleaning or just hot water washing. It is a buffered low pH product that will continue to brighten the surface and deep clean the surface every time it is applied. Unlike high PH products, the surfaces cleaned will stay cleaner longer and not get as dirty over time. This means you will use less product to clean the surface and at the same time increase your workspeed on the job. So, save money on product, the surface stays cleaner longer and you save time on the job. Great combo!
