Remove printing from anodized aluminum

If the ink used in the screenprint process is UV Cured very few chemicals will remove it. The UV curing process basically starts a chemical reaction that cures the ink as a solid like plastic. When I worked as a screenprinter many moons ago we had to heat from a hot air gun and scrape cured ink from the inside of the machines and finish with wire wool. Obviously this is not ideal for what you want to do.

It's the indestuctable nature of UV inks that make them so popular.
 
If all else fails and you are willing to risk removing the anodizing, try automotive polishing compound. There are two grades - red and white. Both can be bought at an automotive supply and you can ask which is less abrasive.

This really is a late resort as it may remove some or all of the anodizing. Much depends on the hardness of the ink.

But the polishing/rubbing compounds are very useful for bringing up a shine in many surfaces, including painted and acrylic plastics.
 
The correct "Scotchbright" pad will work also - it is softer than the anodized coating and harder than the ink.

HOWEVER - some panels are NOT anodized, they are using that same UV cure material, but transparent.

Look at a soda can - not anodized.

Heat will mess up some dark anodized colors... depending on the process used.
