I use Blackfire Conditioning Shampoo when I want to get a good wash in to get off any oxidants. I use it sparingly and end up finishing off with the Polymer Spray as the shampoo alone doesn't leave the smooth feel I am used to....hense the reason it is a conditioning shampoo I guess. The Blackfire Wet Diamond Waterless wash I use in a spray bottle for easy and quick cleaning. Typically, I will always have a spray bottle of Wet Diamong Polymer Spray and/or the Waterless Wash in the back of the car.
