Vacuum the microfiber leather couch regularly to collect loose dirt and crumbs. This will allow the couch to remain looking like new, plus collect residue as it develops, making the cleaning process much easier.
Pour 1 cup of water into a bowl with 1 Tbsp. of mild soap such as dish soap or laundry detergent.
Whisk the soapy water to create a large portion of soap suds.
Scoop the suds with a cleaning rag, then rub onto the microfiber leather surface. Using just the suds will eliminate the introduction of excess moisture, which will potentially cause water marks and stains to develop.
Repeat the whisking and soap suds application until you have cleaned the entire couch.
Scrub the suds into heavily soiled areas with an old toothbrush. This will also allow you to scrub small crevices that are hard to clean with the cloth rag by itself.
