That's a great question, and it's to ask before trying! Generally, it's best to avoid putting solid foam couch cushions directly into the washing machine. The tumbling and spinning motion of a washer can be too rough, potentially causing the foam to tear, crumble, or break apart. The foam can also become completely saturated with water, making it incredibly heavy and almost impossible to dry properly.
Instead of machine washing, the recommended method is to spot-clean or hand-wash the foam inserts. For small stains, you can mix a solution of mild detergent and water and use a cloth to gently dab at the spot. For a deeper clean, you can wash the cushion by hand in a bathtub with lukewarm water and a gentle detergent. Submerge the foam and gently squeeze it to work the soapy water through.
The most critical step is drying. After rinsing the foam by squeezing it in clean water, press out as much excess water as you can without wringing it. You can roll it in a large towel to absorb more moisture. Then, let the foam air-dry completely in a well-ventilated spot, turning it occasionally. Using a fan can help speed things up. It's very important to make sure the foam is 100% dry before you put it back in the cover to prevent any mold or mildew from growing.
