Cola Cleaning Cranks and Crank Arms

By Jon N from the UK

Basic tin foil and cola were all I used to clean the rust off this crank and crank arms. If you pour some cola (doesn’t have to be a main brand, any cola will do) into a cup, take a piece of tin foil about the size of your hand, fold it over so the shiny side is on the outside and then dip into the foil into the cola and leave it for a few seconds. Then take the foil out of the cola and start to rub it on the affected rusty areas as if it was sandpaper. You don’t need to be heavy handed with it as the chemicals in the cola will do the hard work, for hard to reach areas an old toothbrush can be wrapped in foil (remember to have the shiny side out). The sprocket and the arm took me about 20mins and maybe a meter of foil. Be careful if you soak nuts or bolts in cola as if you leave them in there tool long the cola will eat away too much and could affect the thread.
