Hey guys. I bought anew aluminum best track off craigslist a couple months ago. The track has a lot of caked up graphite. Especially on the starting gate and curve. I've read that you guys like to use lemon pledge wipes on the aluminum tracks but I think this is beyond that. Will brillo pads or 0000 steel wool be effective in getting it off. I don't want it to become corroded. One of the brackets underneath the track have already started to corrode. Any suggestions? Thanks
