Written by James Walker · Filed under Car Detailing Quick Answer: Most people who want to know how to mix car wash soap for foam cannon use should start around 1-3 oz of dedicated foam cannon soap per 32 oz of water (roughly 1:10 to 1:20), then fill the rest of the bottle with water.

By James Walker · Car Wash Business Quick Answer: To increase car wash passive income, combine recurring memberships, automated payment and monitoring tools, add-on revenue like vacuums and vending, and pricing based on real operating costs. Passive income here means less daily labor, not zero oversight — equipment and cash flow still need regular checks. A car wash can look like a “set it and forget it” business, but the owners who actually grow car wash passive income treat it as semi-passive rather than fully hands-off. In my experience looking at how sites are run day to day, the difference…

Knowing how to make car wash soap at home gives you a backup option using ingredients many people already have, without reaching for whatever…

Written by James Walker — Car Detailing Quick Answer: To get rid of car wash swirls, wash and clay the paint first, then use a dual-action polisher with a cutting or swirl-remover compound to level the marks, and finish with a wax or sealant. Deep or heavy swirling on older clear coats may need a professional detailer. Swirl marks are one of the most common complaints after regular car washing, and they show up as fine, spider-web-like scratches that catch the light under the sun or garage lighting. The good news is that most swirl marks sit only in the…
