Futons are amazingly versatile pieces of furniture. Perfect for both sleeping and sitting, they get a lot of use in any home. Unfortunately, such heavy use can often lead to a dirty futon, and that's why maintenance is so crucial. Don't fret, however; learning how to clean a futon is easy.
Cleaning a Futon:

Buy a futon cover. Most futon covers are made of a thicker material than bed sheets and are machine washable. You may also use a mattress pad to absorb dirt and sweat. Try washing your cover once or twice a month if it is used regularly.
Rotate the mattress. Rotate your futon mattress regularly. Depending on the type of futon mattress you have, you may have to rotate the mattress more often.
Get rid of surface stains. Use a damp wash cloth, warm water and mild laundry detergent to blot off any surface stains. Avoid soaking the mattress, because too much moisture can lead to smelly mildew.
Deodorize. To deodorize your futon, use a steam cleaner. Check your manufacturer's instructions regarding the use of a steam cleaner on the mattress. Alternatively, a household air freshener can work, too.
Air the mattress out. Hang your futon mattress out in the sunshine to dry. This will refresh the scent of the mattress and allow you to lightly beat any dust out.
Vacuum. Vacuuming your mattress three or more times a year will help keep it free of dust and dust mites.
Care for the frame. Remove the futon mattress from the frame of the bed and examine the joints to ensure none are bent or rusted. If your futon frame is made of hardwood, dust and polish it with furniture polish as needed. A metal frame should be wiped down with a rag.
