Greased lightning is a great product. It is ammonia based so they say not to use it on alumininum, but me, the rebel I am have used it on my stock rims and it works awesome. It has a little chart on the bottle that tells when to use it full strength(greasy parts, engine etc) and when to dilute it. I just kept adding water to the bottle until it was weak. I restored almost the entire car with the bottle. The window rubbers and hoses etc look like brand new. It cleans great, then you put dressing like Mothers Back to Black to add shine.
