What causes burns on aluminum?

If you are asking yourself why your aluminum looks burnt... Then watch this video. This subject is also covered in a separate video on white lines and burns but this video just breaks down burns. Burns are rarely white in color and are almost always yellow, orange or brown in color. In rare cases white does happen but white usually signifies missed areas or missed spots. I hope this video helps stop some of the confusion out there. I get this question a lot in my social media platforms.
