A budding Michelangelo at home creates problems when he takes to drawing on the walls, on the carpet and even on the couch. Lucky for you, even if your child uses crayon, you have several methods -- some green, some not -- to choose from for removing the crayon from the surface of the couch. Use the same cleaning solutions to remove crayon from a microfiber couch as you do with other fabrics around your home. And then go out and buy your Michelangelo washable crayons to make crayon removal much easier.
Baking Soda Method
Saturate a sponge under the running water of a faucet. Get the sponge thoroughly wet, and then wring it out until no water remains but it still feels damp. Sprinkle baking soda onto the damp sponge and clean the crayon-marked area on the couch with it. Repeat the process until the baking soda removes all of the crayon. Dab the area with a clean, soft towel to help remove any excess moisture.
Misted Rubbing Alcohol
Add rubbing alcohol to a fine misting spray bottle. Mist the area until it is slightly damp. Gently scrub the crayon area with a new and damp sponge until the crayon is gone. Repeat as necessary. Let the area thoroughly dry. Once it's dry, rub a soft-bristled brush over the microfiber suede couch to soften the nap and return it to its original look.
Fine Emory Board
Most crayon drawings actually sit on top of the fibers of a microfiber couch, because crayon doesn't bond with fabrics very well. One way to remove crayon, especially if there are not that many markings, is to apply a fine emory board or nail file to the crayoned area. Fine-grit sandpaper works the same way, but you can no longer use the emory board or sandpaper once you've transferred the crayon to it. Rub the emory board or sandpaper in one direction across the crayon to lift it from a microfiber couch.
As a last resort -- because of the chemicals involved -- if other cleaning methods don't work, spray dry-cleaning solvent onto the crayoned area. Let it sit for a bit to soak in before washing the area with mild laundry or dish-washing detergent. Try this method on a hidden piece of the couch first to ensure the solvent doesn't change the color of the microfiber fabric. Verify the mild detergent is an alkaline or vegetable based product before you use it.
Iron a Folded Bag
Scrape off the excess crayon with a kitchen butter knife -- not a steak knife -- and then wipe off the knife with a paper towel to remove the crayon. Heat up an iron nearby. Take a paper bag and fold it over a few times so that it has multiple layers to protect the fibers from getting too hot. Set the bag on the crayon mark and iron over it a few times. Lift the bag to check the stain, and unfold it to access an unused portion of the bag to repeat the ironing method until the crayon transfers to the paper bag. Use caution when ironing the area, because if the iron is set too high it can burn the microfiber fabric.
