).
Things to avoid: Do not use fabric softener when washing microfiber cleaning devices. Softener would act as a kind of wax, recovering the fibers' surface, clogging up the micro spaces that are efficient to trap dusts and also cancelling the fiber's chemical and electrostatic properties. Microfiber can be washed with other kind of textile provided they are lint-free. No terry cloths or dryer sheets for instance! Otherwise lint would clog the fibers as well and reduce their efficiency. If those mistakes have been committed, microfiber should be rewashed in order to recover its properties. Like most plastics microfibers are resistant to a lot of chemical products. However do not use chlorine bleach on microfibers and avoid using acetone (it can shatter polyester fibers) or strong acids (it can shatter nylon fibers
Hope this helps
