We also wash and santize school and church playgrounds
We do wind up washing somethings that you would not think that we would be washing. We recently did some restoration work on almost a 200 hundred year old barn under the flooring all the joists and supports.
We also recently washed battery acid from a hundred feet of sidewalks in front of Rockford Federal Courthouse . Caused by a roll over car accident.
This is the inside of a cow barn that we wash twice yearly the walls, ceilings and floors to sanitize and clean everything Using Hot water and biodegradable commercial cleaning chemicals
