How to Clean Sofas Made From Polyurethane Foam

Polyurethane foam is one of the most common materials used in sofa design. It is durable yet comfortable and is easy to mold around framing. Over time, however, polyurethane foam can become dingy and soiled. In addition, because it is a foam-based product, it readily absorbs any liquid that is spilled on its surface. Cleaning the polyurethane foam in a sofa is an easy job, though it does require extra time for drying before you can resume regular use.

Things You'll Need

• Vacuum Upholstery attachment All-purpose fabric cleaner Spray bottle Hose and spray nozzle Handheld shower head Fan Baking soda Hydrogen peroxide Enzyme-based odor neutralizer

Instructions

1. Unzip the upholstery cover over the foam. Thoroughly vacuum the surface with an upholstery attachment to remove any loose dust and debris.

2. Fill a spray bottle with an all-purpose liquid fabric cleaner. This can be purchased at your local hardware store or in the cleaning supply section of your favorite retailer.

3. Spray the entire foam surface with the fabric cleaner.

4. Place the cushion in the tub or take outside. Rinse area thoroughly with a spray nozzle and hose or handheld shower head.

5. Squeeze (but don't wring) the mattress to remove any excess water. Allow to dry thoroughly.

6. Spray the couch lightly with water and dab with a clean, dry cloth to remove as much of the fabric cleaner as possible. Move to a sunny location to dry.

7. Rub a small amount of baking soda into area after foam is dry. Pour a small amount of hydrogen peroxide over baking soda. Rinse area clean.

Tips & Warnings

• Use a fan to speed drying process. If the foam has pet or other odors, spray it with an enzyme-based odor neutralizer.

• Be sure to test the cleaning solutions in an inconspicuous location before using on entire surface to determine if it will become discolored.
