Coca Cola is an excellent rust buster. If you have a bunch of small objects that need de-rusting, soak them in coke overnight and give them a good scrub in the morning. The properties of coke help to break down the rust particles, making cleaning much easier. You can also apply coke to a chrome finish which is rust spotted – pour some on a rough textured cloth and rub it in a circular motion. Be sure to throw out the used coke when you are done with it or you might be taking a trip to the doctor.
