Customer questions about this product

Can I use bleach on microfiber?
No, it is not recommended to use bleach when washing your microfiber cloths. Using bleach causes the material to deteriorate, reducing the life of the microfiber.
Can I use fabric softener on microfiber?
No, fabric softener should not be used when washing your microfiber cleaning products. Microfiber works so well because of the open spaces in the fibers. When microfiber products are washed with fabric softener, these open spaces become clogged, which reduces the microfiber’s effectiveness.
Can I use microfiber cloths to clean windows?
The simple answer is, yes! Microfiber works well for cleaning any type of glass surface. In fact, it works better than cotton cloths or traditional paper towels on common dirt like fingerprints, lipstick, and dust.

    This cleaning cloth works well for wet and dry applications. It is not too large to be cumbersome. I did notice that it did start to fray a bit after a couple uses.
