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

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