I recently purchased a used set of Honda XL70 foot pegs off of EBay. Aside from rust, they have a lot of oil or grease on them. I want to clean them up for painting. How do I get all the grease off of them completely prior to painting? Dawn? I may be getting them blasted but I don’t think that will remove all the oil. These are the knarly, all metal type with the teeth that stick up. Thanks
