When it comes to maintenance, if there are any small stains, just use water and a dry cloth to spot - clean. Avoid using harsh chemicals or soaking the topper. Also, make sure to keep it away from sharp objects that could damage the foam. With proper care, this topper will keep you comfortable for a long time.
