They were extremely profitable in the 1970s and when automated car washes came along in the '80s and '90s, many people made a lot of money operating them. I own 2 car washes in wisconsin and both have automatic and manual bays.
90% of car washes are owned by a small business owner.
How much do car washes make. Average car wash owners usually spend $100,000 up to $250,000 for the land alone. Average startup costs per car wash: Remember, the more employees you have, the less money you make.
