How to wash microfiber cloths without softener
Wash microfiber cloths according to their labels and avoid fabric softeners, bleach or high heat when not permitted.
Fine microfiber strands capture dust and moisture, but accumulated dirt and incorrect laundering can impair performance. 3M's guidance for a particular Scotch-Brite microfiber cloth excludes fabric softener and bleach. Temperatures and dryer rules for other cloths must be checked separately.
