When cleaning Napa Pi with ice silk seat covers, a combination of dry cleaning and water washing should be used. 

Dry cleaning: For the Napa leather part, if there is slight contamination on the seat cover, you can use a clean towel dipped in water to gently wipe it, or use a volatile dry cleaning agent to gently wipe it and air dry it in a timely manner. When cleaning, neutral or low alkaline detergents without chlorine bleach components should be used, and the water temperature should be controlled at around 30 degrees Celsius. Avoid rubbing vigorously, especially avoiding the use of hard brushes, to prevent damage to the leather. After cleaning, you can gently wipe the surface with a wrung out wet towel and then air dry it. ‌
Washing: For the shredded ice, the cleaning method is more flexible, and it can be dry cleaned or washed, but the dry cleaning effect is better. If water washing is chosen, a low alkaline cleaning agent should be used and soaked in warm water at around 30 degrees Celsius for 10 minutes. After gently brushing with a soft bristled brush, fold the seat cover and place it in a dehydrator for dehydration. Then, place it in a cool and ventilated place to dry, avoiding exposure to sunlight or forcefully wringing it out. ‌
