As a sectional sleeper sofa requires care, you’ll want to check the cleaning instructions from the manufacturer before taking on the task. Every material has different properties and the upholstery of your sofa is going to define the best way to keep it clean. However, you’ll want to regularly vacuum the sofa to remove dust and other particles that may settle on it. You should also be extra careful about spills and stains if your sofa is made of linen or other absorbing materials. Investing in routine professional upholstery cleaning is recommended.
