Nothing will take out the scratches BUT if you clean real well you can clean out the dirt and the shine will tend to blend the scraches in so you do not see them as clearly. They are not like swirls on paint . You can not polish them out. Patpur and I had problems with our Mercedes from women with high heels scruffing the door sills. If you want perfection you will have to replace them. I live with the fine scraches but they look 100% better. I used Mothers Mag and Aluminum polish on the Mercedes and Xfire. It was about $5.00 and worth the while. Plan on doing it about 10 times or more. The first time it will get really black from oxidation . Do not put too much on it to start with. The key seems multiple applications and rubbing not amount of product. Hope this helps.
