Any cleaning company that doesn't use microfiber is really missing out. Whether they use feather dusters that spread dust or cotton cloths that scratch surfaces or leave lint behind, these outdated methods create more work for the cleaner. I started using microfiber for general dusting, polishing and sweeping years ago and have never looked back.
A synthetic fabric made from polyester and polyamide, I use microfiber for its ability to attract dust and not leave lint behind like traditional cloths. Other products like 3M's Doodleduster cloths have an above average ability to attract dust but are quite expensive and delicate.
Microfiber cloths come in different colors to prevent cross contamination so you won't accidently polish somebody's desk that you cleaned a restroom with. The most common microfiber cloth, blue, has a slight texture to clean windows while yellow, green or red cloths can be used for polishing and general cleaning.
Many cleaners use the blue window washing cloth on office windows and mirrors. They are also perfect for wiping up excess solution left around edges and corners from squeegee window cleaning. But make sure to have a healthy rotation of clean cloths to avoid minor streaking or dotting.
The first microfiber product I ever used was a dust mop. Anyone that has had an old school dust mop on a janitors cart knows what its like to choke on dust bunnies and debris as you move along. Microfiber does a great job of attracting and keeping dust on the pad, and like the cloths, can be washed hundreds of times.
Microfiber cloths and pads are inexpensive and readily available. This is very helpful on weekends when most janitorial suppliers are closed and you need some new cloths for a weekend account.
I am always on the lookout for new technologies that save money and make our job easier, and microfiber has done both.
