How do I clean the seat cover and harness?

Soft goods (including the headrest pad, seat pad, head pillow, body pillow, harness covers, and buckle cover) should be machine washed separately in cold water on a delicate cycle with no chlorine bleach, then tumble dried for 10–15 minutes on low heat and removed immediately. The harness can be wiped clean with mild soap and water and allowed to air dry. Plastic and metal parts may be wiped with mild soap and water using a soft cloth — do not use abrasive cleaners or solvents. (Page 120)
