What do you guys use, if anything, to sterilize/disinfect artificial turf fields. How often do you do it? The disinfectant salesman says twice a month for normal use. Basically this equates out to a trailer load of product every year. The bean counters got a good laugh when I gave them a quote on that amount of product. I have also been told that using that amount can damage the backing, and is simply unnecessary. Spot spraying on a regular basis (on the spot where someone blows lunch, or immediately around the benches) and then a complete spray once a year, maybe twice if it gets heavy use. Sound good??
