3 Steps to Get Sand Out of Microfiber Towels
Let the towel dry completely Sand sticks to wet microfiber, but once dry, most of it shakes right off.
Shake it outside Take the towel outside and give it a good snap and shake to remove loose sand.
Wash with care If sand remains, wash with a little detergent only — no fabric softener, which ruins microfiber. Air dry or tumble dry on low.
