Even the best socket sets will need to be cleaned from time to time. To clean rusty or dirty sockets, fill up a bucket with white vinegar and let them soak for at least a full day. The acidic vinegar will eat through the rust and make it easier to rub off with an abrasive pad. You can also use degreaser and a rag or toothbrush to wipe off debris. Before putting the sockets away, make sure they are completely dry.
