Oil eater is a great degreasing product. HD has it on their website (maybe the store too), Costco used to carry it, and still does here and there but it's very hit or miss. We use it at work (commercial bakery) and I think it is the best degreaser on the market. It doesn't leave any white film as others tend to do. Not sure if the ZEP degreaser does or not but wanted to offer up oil eater as an option.
