Aluminum cranks -- cleaning and polishing?
So, I decided to give my bike a thorough cleaning and relube last weekend, and everything went fine except for one thing...
It appears that over the last year or so that either my sweat or road salt has made corrosion marks on my cranks. These splotches won't buff out with a t-shirt rag, and now I am starting to think about other treatments.
So basically, I want to ask if anyone has any ideas.
I don't think this is totally an appearance thing, its also about safety-- it is really important to be able to periodically inspect the cranks for cracks, and now with these whitish spotches that is getting hard to do.
