However, cleaning like this is really a bit troublesome for ourselves, but it is definitely not a problem for the car wash shop, which has special cleaning tools. But in my impression, the car cushion you mentioned should also be the kind you put on the seat. Not too big. You can just take it off, wash it and dry it yourself. Generally, there are suits in winter and summer, and two sets are changed every season, which are generally easier to clean, as long as they are not difficult to clean. For example, there are wrinkles and lines on leather, which is really difficult to clean, so special leather care is needed.
