A number of home remedies exist for cleaning microfiber that reduce the need for harsh chemicals, and extend the life and look of the furniture.
Maintenance
Vacuuming the couch on a weekly basis will remove general debris, dirt and dust. Microfiber is a resilient fabric and can handle general vacuuming. It will not pucker or tear from such treatment.
A lint roller used for brushing hair and debris from clothes provides the ideal quick cleanup for the microfiber couch. Roll along seats and arm rests to remove pet hair and food crumbs. This will help maintain the look of the couch between more rigorous cleanings.
General Cleaning
Mix warm tap water and a few drops of household dish detergent into a clean bucket or bowl. Stir gently to create bubbles. Use a clean lint-free cloth dipped into the soapy water mixture and rub gently over the surface of the couch. Apply even pressure and work in a circular motion. Remove residue soap by wiping with a clean cloth that has been dipped in plain water and is well wrung-out. Alternatively, use a small drop of laundry detergent in the water instead of dish detergent.
Consider a seasonal or annual steam cleaning of the couch using your home steam-cleaning machine. This will help release embedded dirt and odors and revive the look of the couch.
Stain Removal
Odor-causing stains, such as pet urine and vomit, can leave unsightly stains and smells on a microfiber couch. Remove urine by mixing equal parts of white vinegar with distilled water in a clean spray bottle and applying to the stain. Use a paper towel or cotton cloth to blot the stain. Apply a teaspoon or two of baking soda to the stain to absorb the odor and allow the entire area to air dry. Vacuum remnants of baking soda away and repeat if necessary. A quick hand rub over the area will loosen any embedded soda dust.
Take vomit stains out of the couch by first removing any surface debris with a dry paper towel. Applying vinegar mixed with hot water and a little dish detergent and scrub gently with a soft bristled brush. Allow to air dry.
