This DIY video on how to clean a microfiber couch recommends cleaning with alcohol in a spray bottle. I can tell you as a professional upholstery cleaner in Tampa FL I have seen my share of stained microfiber upholstery. I would not recommend spraying straight rubbing alcohol onto your micro fiber furniture as a cleaning agent. I would definitely not want to breathe in rubbing alcohol after it has been atomized by a spray bottle.
Microfiber is polyester based material that water spots easily if not wetted completely. Polyester is a great material for upholstered furniture with one drawback, it easily soaks up oils. Skin oil, oily soils, and greasy foods can easily find their way on to your favorite couch or chair. These stains can be easily and effectively removed with a DIY cleaning solution.
Here’s a professional upholstery cleaner’s take on how to clean a microfiber couch. Take 4 cups of water, add ½ teaspoon of your favorite dish washing detergent (I recommend Dawn original scent), and a teaspoon of vinegar. Mix them all together and add them to a spray bottle. The dishwashing detergent will breakdown the grease in your couch stains while the vinegar will lower the pH in the cleaning solution, making it more acidic.
The combination of a mild detergent and acid will easily remove most spots from your microfiber upholstery. Spray the entire surface evenly and then use a clean white towel to spread the solution across the surface. Then take another clean white towel and dry off your couch. Wipe in the same direction to ensure all the fibers are laying the same way, making the surface look smooth. Then let it dry thoroughly before sitting on it.
