I did that all winter long and this spring, the pipes were shiny. Great tip!
used to live Louisiana and if you did not keep the bike inside during winter, the pipes would start to pit rust.
Once that starts it is all over.
Polishes work but ones with an abrasive will eventually hurt.
SOO
best is to make sure there is no way to get moisture inside at night and that means climate control
I have even tried the "park it on a piece of plywood" trick that is suppose to keep moisture from getting inside the pipes. Wife's tale at best.
