This Ritz Clean Microfiber Multi-Chore Kit is everything needed for a clean home. Each cloth is unique in its weave and feel and its application for the home. Microfiber is made of fibers 100 times finer than a human hair. These fibers create a high density weave with greater surface area making each cloth a highly efficient cleaner. Use these cloths wet or dry and there is no need for cleaning solutions. They reduce common allergens by picking up more particles, dirt, and debris than other wiping products. Additionally, they inhibit much of the common bacterial growth than conventional cloths. Contains 4 cloths that are machine washable and reusable.
