Startup cost: $50 - $500

Setup costs range from $50 to $500 depending on the approach taken. At the minimum end, you would need basic car cleaning supplies like soap, sponges, and towels, which can be purchased inexpensively. On the higher end, investing in professional car washing equipment, signage for advertising, and possibly a website for online booking could increase costs. Optional expenses may include setting up social media ads or hiring help for busy periods. Hidden costs could include water usage fees if washing cars at a commercial location. Online feedback suggests that costs can vary widely depending on the level of professionalism and scale you aim for. For a friend looking to take this seriously, I would recommend budgeting around $200 to $300 to cover essential supplies and initial marketing efforts.
