I have several steel kettlebells that I keep outside in the carport where I train. They had decent rust on the handles. Apply wd40 to them and leave it on for about half an hour. Use one of the medium sized wheels on the drill. Worked great. In less than 10 minutes I was back on steel. No sign of the spoked wheel breaking after two weights. You can get a box full of these for less than $10? How can you be wrong.
