Hi all,
I’m looking for some guidance on how to address a problem with the external black anodised frames on my house Stegbar windows. The windows were installed about 25 years ago, and over time, the anodised coating has developed signs of oxidation. The underlying aluminium is still in good condition, but the black surface has started to look dull and weathered.
I’ve attached a few images to show the extent of the oxidation. You can see that while the aluminium frames themselves are structurally fine, the appearance of the oxidised coating is detracting from the overall look of the house.
Has anyone dealt with a similar issue, or do you have any recommendations for bringing these anodised frames back to life and maintaining the finish? Any advice or suggestions for products or methods would be greatly appreciated.
Thanks in advance for your help.
