A normal car wash, by my calculations, is not expensive. But there is a disadvantage - it is a little slow. I asked as soon as possible. We managed it in an hour (without a vacuum cleaner) for those who have time, the price and quality correspond.
The sink is nonsense, the prices for it are space. Nothing special — go to the self-service car wash. Spend 4 rubles and 15 minutes and it will be better
