Couch covers can be custom-made or purchased from retailers and are made with machine-washable fabrics. Because a couch cover is a piece that will be laundered frequently, it is best to choose fabrics that can withstand the frequent cleaning, such as cotton and polyester. Always consult a cover's tag to confirm cleaning directions, or consult the maker for custom-made pieces.
To keep a couch cover in the best shape, wash it in cold water and on a gentle setting. This will also help minimize color fading. When washing, launder the cover by itself. It is safe to use the detergent that is used for general laundering. Do not launder a couch cover that clearly indicates it must be dry cleaned. Always follow the manufacturer's guidelines.
Just as with clothes, to increase the chance of completely removing a stain, pretreat the fabric. The first step in cleaning a liquid stain is to soak up the spill with a clean towel or cloth. For hardened stains such as mud, gently sweep them away with a brush, but avoid rubbing the stain, which may spread it. Hot water and soap will actually set stains in, rather than get them out. A petroleum-based solvent spray is the best product for pretreating oil-based stains such as peanut butter.
The crevices of a couch cover are ideal spots for dust mites or crumbs to collect. To remove them, frequently vacuum the fabric. To dry a couch cover, either air dry it or use the lowest dryer setting possible.
