I have used another product that is MUCH cheaper and is safe for the enviroment. It's called "Oil Eater". I picked up a Gallon of this stuff at Costco and it was only $8.00. You spray it on, let it sit and hose it off. As David stated, for gunked on areas you will need a putty knife or a steel parts brush to get it clean.
