That tower will be easy to clean. Take the faucets off and soak them in HOT Oxyclean. Then rinse them and polish with Brasso. It will take about 15 mins per faucet but they will shine when done. It is hard to see in the pics but looks like the faucet valves are chrome or stainless. That would be a nice freebee. Mine were all brass but I sold them on ebay for $10 per. I already had Stout faucets and Perlicks. The tower should be cleaned with Oxy for beer stains then Brasso for the rest. If you want it to really shine google for brass workers in your area. They will polish, remove scratches and laquer it. It will look new.
Good luck and post the finished pics.
