While the provided links confirm that cleaning foam sofa cushions is a common question, they don't offer the specific step-by-step instructions. Not to worry, I can certainly walk you through how to get your cushions fresh and clean!
First things first, remove the foam inserts from their fabric covers. You'll want to wash the covers separately according to their care tags. For the foam itself, start by giving it a thorough vacuuming on all sides using an upholstery attachment. This will pull out any loose dust, pet hair, and crumbs that have settled into the foam.
For light stains or spills, spot cleaning is your best bet. Mix a small amount of mild laundry detergent or dish soap with warm water. Lightly dampen a clean cloth with the solution, wring it out well, and gently blot the stained area. Avoid rubbing, as that can push the stain deeper into the foam. After blotting the stain, use a separate cloth dampened with plain water to "rinse" the area, then blot it dry with a clean towel.
If your cushions need a deeper clean or have some lingering odors, you can try a couple of gentle methods. One easy way to deodorize them is to sprinkle a generous amount of baking soda over the entire cushion. Let it sit for at least an hour, or even overnight, and then vacuum it all up. Alternatively, you can lightly mist the foam with a solution of equal parts white vinegar and water. The vinegar smell will dissipate as it dries, taking other odors with it.
The most important step in this whole process is drying! Foam acts like a giant sponge, and any moisture left behind can lead to mildew. The best way to dry the cushions is to let them air dry completely, preferably outdoors on a sunny, breezy day or indoors in a well-ventilated room with a fan pointed at them. Gently press on the foam to squeeze out excess water, but never wring or twist it, as this can cause damage. Make absolutely sure the foam is 100% dry before you put it back into its cover.
