Marshmallows are a fun treat, but they can leave sticky stains on your outdoor sofa. To prevent these stains, consider using a protective cover or blanket when enjoying marshmallows outdoors. If a stain occurs, act quickly by scraping off excess marshmallow with a dull knife. Then, mix warm water with mild dish soap and gently blot the stain with a soft cloth. Avoid rubbing, as this can spread the stain. For tougher stains, a solution of white vinegar and water can help break down the stickiness. Always test cleaning solutions on a hidden area first to ensure they won’t damage the fabric. Regular maintenance, like vacuuming and spot cleaning, will keep your outdoor sofa looking fresh. By following these simple steps, you can enjoy marshmallows without worrying about lasting stains on your furniture.
