This stuff works great!  I was unable to remove the rust from the bottom rack as directed because if I did there wouldn't be anything left to put the goop on. The dishwasher is 22 years old so buying a bottom rack for it is impossible.  I bought two more bottles as well as the tines to continue trying to save the rack.
