Some environmental solutions are so simple and effective you wonder why everybody doesn’t know about them. Here’s one every school facility director should know about: microfiber cleaning cloths.

Microfiber synthetic cloth was invented in Sweden in the 1980s and its popularity quickly spread to environmentally-aware consumers across Europe. Microfiber can be used to clean camera lenses, eyeglasses, furniture, mirrors, floors and almost anything else using only hot water, although it can also enhance the performance of cleaning products. The cloths also come in a wide variety of colors, making it easy to avoid cross-contamination when cleaning.

Many hospitals, schools, office buildings and institutions are using microfiber cloths because of their economic and environmental benefits. The downside: the fibers are manufactured from petrochemicals. However, in this case, the use of a small quantity of petrochemicals may be off-set by their extreme cleaning efficiency.
