If you have enough time and space in your house and are ready to make an effort and bear the expenses, it is better to wash your car at home. But if you have water issues at home and you also do not have enough space to complete the car washing procedure at home, then it is better to take your car to the service stations and get a machine equipped wash. It is always better to go for the former one, but if at all it is not possible then you can take the car for a machine wash!
