It's just chrome. Any good quality chrome polish works great. I like Mothers. It seems to do the best at cleaning and polishing. Don't use a metal polish, they have a mild abrasive that will scratch (dull) the chrome.

the best thing i found to deal with chrome, is sealing it.

wax wax wax.

i have built a few custom bikes and the metal under chrome can corrode rust bubble and just look like crap, several coats of wax will seal it up.

I just now finished polishing my 70's Ludwig Super Sensitive shell with Mother's Chrome Polish. Just about all good polishes will leave a protective coating on the chrome.

My SS is a mid-to-late 70's with exceptional chrome, with only the very beginnings of some areas of chrome bubbling. No flaking, pitting or anything else. Talk about lucky! Makes me laugh at the two "reliable anti-galvanic" stamps on the inside of the shell. Talk about your oxy-morons!! Still, The shell is in exceptional condition and I just completed disassembled it today to begin a preventive polish on all the chrome. Once complete, pictures will be posted!
