You can spot clean your foam by taking a wet rag and your favorite upholstery cleaner to the product — we've tested Folex and like it the best. Once you're done, make sure that your Nugget foam is completely dry before putting the covers back on. You can set the foam near a fan or open window to help speed up this process.
For future accidents, we highly recommend protecting your foam with a Nugget Liner Set, made from non-toxic waterproof material.
