A simple diagram highlights the differences between microfiber cloth and cotton fiber. Microfibers are tiny fibres that have been slit into millions of finer fibres. Each cloth is made up of tens of thousands of tiny storage compartments that pick up dirt, trap waste, and leave a streak-free surface. Microfiber can collect and absorb more dirt and bacteria particles than any other fabric. It can absorb up to 7 times its weight in dirt or liquid. Choosing the right towel is extra important!
