Optimum No Rinse Wash & Shine (ONR), there was no choice other than to use regular car wash shampoos that impact on water restrictions, and in many areas these shampoos are simply no longer allowed. No more! Optimum offer the only alternative product that cleans AND protects your vehicle and protects the environment too. It will reduce the water usage to a fraction of a conventional car wash. No Rinse Wash & Shine is the most technologically advanced car wash system to date, that requires just a single bucket of water to wash an entire car. Optimum No Rinse & Shine (as the name suggests) does not require rinsing with a hose since there are no soapy surfactants to wash off into the storm drains.
