You may think that cleaning your own mess is hard, but imagine cleaning up for a whole building of other people and not choosing what products to use. Office cleaners have a cart full of cleaning products that they have to use, that have been pre approved according to this article. Office cleaners should read the labels correctly and only dilute products when it says to, you never know what two chemicals you may be mixing together and you wouldn’t want to lose your job over it. If one product doesn’t seem to be working, then try other one. Don’t mix products or use twice as much, which can be wasteful and dangerous. Different products will work in different situations and eventually you will see which ones work best on what. Office cleaner’s carts should have everything you need from brass polish to “liquid air” for cleaning computer keyboards and other computer parts. When in doubt about a product, ask someone for advice. You don’t want to be cleaning a surface not knowing what might happen.
