I know a lot of guys on here have aluminum pulleys on their stangs. Every pulley on my stang is aluminum. I was wondering is it safe to polish them? I know that the inner and outer sides are fine. What about the part of the pulley that touches the belt? I am asking this because my idler and water pump pullys, which are both smooth, could use a cleaned and I am not sure if I should polish the actual part that touches the belt. I'm not even gonna try to clean the inside of the grooved ones. Any ideas?
