If you’re looking for another creative way to make extra money with your car, consider becoming a mobile car washer/detailer. Many people don’t have the time or inclination to clean their cars, and that’s where you come in. With a few basic supplies like soap, sponges, towels, and a portable vacuum, you can offer car washing and detailing services at customers’ homes or offices. This side hustle is especially appealing because you can set your own hours and work as much or as little as you want. You can market your services through local community groups, social media, or even on platforms like TaskRabbit. As your reputation grows, you can charge higher rates for more detailed services like waxing, interior cleaning, and stain removal, making it a profitable venture that can be done right from your car.
