If you have a WASHABLE couch pillow, then yes, you can cleanse it in your washing machine! However, suppose your couch pillow is made from a blend of materials (like cotton and polyester) or has a removable cover.
In that case, we recommend dry cleaning as this will ensure that your cushion remains clean and free from damage. If you want to hand wash it instead of putting it through the washer and dryer, simply use cool water with mild detergent and let the air dry.
If there’s an odor problem on your couch cushion, then we suggest trying out one of these tricks. Leave a bowl of baking soda near the problem area for several days; sprinkle some baking soda on top. Then, put down layers of newspaper before putting down layers of white vinegar (the smell should go away after 24 hours).
