Optimum No Rinse for Handwashs I live in the middle of Manhattan without access to a hose or easy access to a car wash. I've been handwashing my car using Optimum No Rinse Wash & Shine (ONR) and two buckets of water -- one for the ONR/water solution, and one filled with clean water to clean the sponge. No rinsing of the car is necessary. And because of its high polymer content, I haven't had a problem with scratches occuring while washing. I think it's great stuff.
