Remove the microfiber cloth covers from the cushion. Before proceeding read the manufacturer's cleaning suggestions on the tag; some may differ from this process, which is a general guideline to gently cleaning and drying microfiber cloth covers without shrinkage or damage to the cloth.
Turn the cushion cover inside out and submerge in lukewarm water. Lukewarm water is warm enough to activate the detergent but not hot enough to cause shrinkage of the fibers.
Add 1 tbsp. of a gentle laundry detergent, such as Woolite, to the water and swish it around with your hand. Because the water isn't hot and you are using a gentle detergent you can use your hands to gently agitate the cloth cushion cover in the water for about five minutes.
Lift the microfiber cover from the water and gently wring. Place the cover aside and repeat with any other cushion covers you wish to clean.
Drain the detergent water and rinse the cushion covers thoroughly under lukewarm running water, making sure to get all detergent residue out of the fabric. Once all of the covers you are washing are rinsed you can set them aside while you set up your flat drying rack.
Pick up each cushion cover individually and snap it up and down sharply to straighten out the shape and remove the wringing lines. Spread the covers out on the flat drying rack and place in an undisturbed area to dry completely. Once the covers are dry, flip them right side out and snap them up and down to make them look crisp and fresh like new before you put them back on the cushions.
