After each use: Rinse the microfiber cloth with warm to hot water (or whichever water temperature is recommended on the care label) for 10-15 seconds to flush out dirt. If microfiber is especially grimy, you may want to rinse it until the water runs clear. Once rinsed, the cloth is ready to use again.
Once a week: Microfiber cloths that are used daily should be machine-washed every week. Rinse them first to flush dirt from the fibers, then toss them into the washer with your regular wash. Do not use bleach (it will damage fibers) or fabric softener (it will clog fibers). (For cloths that aren’t used that often, wash them when they look dirty or leave behind traces of lint or dust.)
Follow care instructions for drying. Some items, such as floor and wall duster heads, have specific care instructions, so always check the care label first.
If cloths become ineffective or if they start to smell, boil them in water and one-fourth cup of baking soda for 10-15 minutes.
