Review on P21S 13005L Auto Wash Canister by Mark Quarterman

I used this to clean the engine bay of one of our cars and was very impressed! I have taken all necessary precautions to clear the bay for anyone reading this who cringes to think that I am actually spraying water to wash off after application. It needs to be washed off after application, but it doesn't take much time to remove dirt and grime. I've also avoided using the washing machine because the thought makes me cringe. I just used a light hose rinse and dried the bay with my air compressor. I've also used this in the wheel arches of another of our cars and they cleaned up really well too. To each their own, although I recommend it for automatic deep cleaning in hard-to-reach places.
