What should I use to clean under the hood of my dart

I'm doing this rite now. Gallon of degreaser and a spraybottle. I am repainting so i am using wire brushes from harbor freight. If you have a lot of grease like I did scrape first before even bothering with degreaser. scrape the crud out the best you can then hit it with degreaser and a brush to get whats left. Patients is the key. I'm going to use some wax and grease remover on everything after it has been fully degreased. Then work on the rust repair and paint.
