autosol is good I used to use it. But it's all elbow grease. If they are really tarnished a good way to get them back to a dull finish is using a polishing compound that isn't to abbrassive. Followed by autosol to bring up the shine. has to be done in two steps. have plenty of clean soft cloths to buff up the aluminum. microfibre is good.
