Steam and high pressure works well for washing and cleaning up garbage dumpsters and the concrete pads around trash areas. Grease and spills build up fast in these areas at restaurants, hotels, retail stores, and many other locations.
Watch out for maintenance crews using cold water pressure washers. They can’t achieve the same results you can get with steam and hot water, and often will damage (pit out) the concrete while trying to get out tough stains. We always use steam and hot water to blast away the gunk and grime that builds up around garbage dumpsters and trash receptacles.
