Tower Speaker Cleaning

Has anyone had any luck cleaning their cans? Mine are faded and not shiny anymore and have some scratches. Any suggestion would be great.

red,
You didn't specify but I'm assuming you have polished aluminum pods. In order to be spun (shaped) or cast, it is a softer and more vulnerable aluminum prone to oxidation.
When they get heavy oxidation it really takes some elbow grease to restore them.
Spot address the scratches with a stronger polishing compound. Then buff out the entire pod with the finest polishing compound. Plenty of choices at an automotive supply.
Maintain the pods with a pure carnuba wax (no cleaner wax). Use only a terrycloth or worn cotton cloth. Apply several times per season.
Avoid paper towels when cleaning--too abrasive.
Powdercoating is a good long term solution. If it is a cast pod, it really needs to be baked in an oven (by the powdercoater) beforehand.
