Some businesses only clean when they “notice” their office start to get dirty or only clean once or twice a month. Both of these strategies face significant problems. First, as someone who is regularly in your business, you will not notice the kinds of uncleanliness that a first-time customer or visitor would notice, leaving your business looking dirty to your most important audience. More importantly, once dirty, the longer you wait between cleanings, the costlier and more difficult it will be to return your business to a clean condition.
