When you say contaminates; if you are talking about water spots, no not necessarily, water spots are caused by minerals and contaminates that are left after the water evaporates. It does not take long at all for these to eat through the microscopic layer of protectant and start etching into the paint. I also have a black car and a CR spotless. I rinse down with regular water, wash with regular water, and do a final rinse with the CR. I then blow dry with a leaf blower. Then I go over the car with Pinnacle souveran spray wax and a few quality plush MF's, no spots. Remember if your CR is reading .020 or more change the resin. If your car gets rained on you WILL get water spots (you can see them on flat black, they are there). Sometimes, if you get to it quick enough washing, rinsing with the CR, and using the Souveran Spray wax will remove them. Other times if you wait to long, or if the minerals are heavy, a paint cleaner may be the only option for removal...Remember to rewax where ever you use the paint cleaner though.
