My Cassette is rusted pretty nasty, and instead of switching it out (I do not have the tools to do so) I'm gonna try and get the cassette to the best physical shape possible. Now I've already used some bike spray cleaner intended for cassettes, chains, and disc brake rotors and that has seemed to smoothen the spin. But just wondering if there is anything else I can use. This is my first time restoring a bike, done for the sole purpose of learning more about bike components and what I can do to fix them. So any suggestions will be appreciated. I'm considering using lime-a-way for this.
