Adam's Christmas Tree Car Shampoo is here for a limited time only. A flagship product that our customers love now features a pleasant cinnamon scent! Your car washing process will smell of fresh-baked cinnamon rolls while you clean. Use Car Shampoo in your foam cannon or foam gun for extreme suds! Otherwise, you can simply add a few ounces (2-4) to your 5 gallon bucket while washing by hand.
