Hand washing works best for cleaning microfiber cloths that have been used to clean dry messes, such as for dusting. For dirtier cloths or those used to mop up spills, you will need to machine-wash them.
Don’t use detergent or any other cleaning products for this method. To get dust and light dirt out, all you need is clean water and a little agitation.
If this doesn’t work to get the dirt and dust out of the cloths, then you will need to launder them in a washing machine to clean them thoroughly.
Avoid drying microfiber cloths in a drying machine. Drying machines are full of lint and dust that the cloths will just pick up. If you absolutely must dry them in a machine, then tumble dry them with no heat and apart from other items.
Wash microfiber cloths used to clean in the kitchen, bathroom, or used to clean liquid or greasy messes after each use.
Certain types of fabrics will rub against the cloths and break down the microfiber bristles which will decrease their effectiveness as well.
When washed correctly, microfiber cloths will survive 100-500 wash cycles and retain their effectiveness. Replace them when they start to feel rough, like normal washcloths.
Microfiber cloths dry very quickly. They should be dry and ready to use again within an hour. If you can’t wait this long for them to dry, then only tumble dry them with no heat and separately from any other items.
