Cleaner/Protector????

[Irish]

What has everyone found to be the BEST cleaner/protector for chrome & polished aluminum? This Florida climate has me cleaning more than riding! I'll clean my chrome/aluminum one day & it seems as if two days later it's pitting again. My ride is kept in a carport (not a closed garage) & even tho I always kept my bike in a garage in NH , I never had so much trouble with corrosion. Irish
P.S. The thing that really suprises me is that the polished aluminum does it as much as the chrome!
