Looking for a great degreaser then get Pinkstuf. A gallon is like $10 and it is the best I have tried. Cleans engines awesone, tires wheels, tar, paint if diluted and brightens the paint also, etc. Also I do mechanical work and it cleans greasy hands better than anything and is safe too.
Carquest, Robbinns auto, VIP auto parts sell it. I could not be without this one and I have been using it for 10 years.
