Is there another method that machine shops use to clean blocks that will get rid of rust in the water jackets along with all the grease and grime?
A real hot tank will dissolve the rust. Unfortunately, due to environmental requirements, most shops have stopped using real hot tanks and instead use steam cleaner tanks. This gets the crud off but doesn't touch the rust.
