So, you guys believe that they are just scratches and the like?
I personally don't care what it looks like, but should I just try to remove it to make sure that that they are scuff marks? i.e. Would burn marks not be able to be removed by simply wiping it down? Otherwise I just plan on leaving them on, I just wanted to make sure that it's not burning or anything, hence my post.
Think about it. If it were burn marks, what was burnt? Theres nothing that could melt or burn. the aluminum isn't melted (and that'd be impressive if it was), so its pretty much impossible to be burn marks.
If it is burn marks, they will have left a weird texture where they burned. If the edge feels normal besides the marks, its not a burn.
