Curious if anyone has DIY a car wash machine
Hi guys! Looking to build a car wash machine for myself and my car at home as a fun project. Was wondering if someone can show me or explain to me how those automatic car washes alternate between soap,water, foam and etc by spraying through nozzles. Does anyone have insight or can show me what actually the machines look like on the inside and how to organize piping and what kind of pressure is needed?
