How do I clean the seat pad and harness on the Maestro Sport?

The seat pad can be machine washed separately in cold water on a delicate cycle, then tumble dried for 10 to 15 minutes on low heat. The harness straps should 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 and dried with a soft cloth — do not use abrasive cleaners or solvents. (Page 50)
