We recommend that you launder your cloths in your washing machine approximately every week or two depending on use, and air dry or dry in the dryer are both fine! Some tips to remember:
To deep clean, remove stubborn stains, or to remove odors from cloths, Norwex microfiber can be boiled for 10 minutes to allow fibers to swell and release the debris. You can use a solution of 1/4 white vinegar to 3/4 water when boiling.
This usually means that you have something ‘clogging’ the microfiber and it needs to be deep cleaned to eliminate that residue. It may be fabric softener residue, soaps, or mineral content from your water.
