Has anyone used Dri Wash on theirs cars? A friend of ours swears by it and you don't use any water . Any comments on this??
The Prius is incompatible with dry washing process. Dry washing causes a static build up of energy that can short out most of the electronics, including the battery. It's in your owner's manual on page 147. Just kidding.
Don't know about that but Optimum No Rinse (ONR) has been used successfully here and I've recommended it to another member here who has been satisfied with the product.
