MOTUL E6 Chrome & Alu Polish 100ml From  €11.54

Its a very good polish, from aluminium it removes even the stuff you dont see, but you see how dirty the cloth gets after it, for chrome is not perfect, it does give shive but its nothing to get excited about. If you are looking for amazing aluminium dirt or grime or grease cleaner then i think its the best there is, but for polishing chrome i would give it 4/5. Keep in mind that it is more of a cleaner than policher.
