What he said, OR Wesley's tire cleaner, and the car wash. That stuff works well. I use it often. #1, Use it full strength, don't dilute it, it won't work. #2, Don't breath the spray from the bottle, it will make your kids be born necade...LOL. All joking aside don't huff it, it is pretty potent stuff. I use it because a spray bottle of it it less than 3 bucks at Wally World, it works good too. You can clean your tires too. It does a lovely job of bug removal at the car wash too. It does take the wax off though, if you wax your truck, be aware of that, and don't leave it sit on your vehicle either. Spray it on then wash it off... Oven cleaner is expensive.
