Aluminium window frame restoration
Has anyone seen this kind of corrosion/pitting on aluminium window frames?
We’ve noticed this pitting/corrosion across a couple of our aluminium window frames and I’m trying to figure out the best way to restore them.
My suspicion is that it may be from when the house was rendered, possibly the renderer didn’t properly protect/seal the windows and the render has reacted with the aluminium.
Has anyone experienced something similar and successfully restored or refurbished frames like this?
What products/process did you use (e.g. sanding, aluminium restorer, repainting, etc.)?
Would really appreciate any advice or experiences before I go down the wrong path!
