How would I remove these "white" stains.
I have multiple of these anadized aluminium extrusions with these white cloudy stains and want to make them stain free. Im also not sure what these stains are, I only persume Calciumoxide.
The methods I have tried after all methods I dried them with a paper cloth:
* Acetone and scrubbing with a toothbrush
* Warm water and soap
* IPA and scrubbing with a toothbrush
* Vinegar essence(25%), waiting 10min, scrubbing
* Natriumhydroxide(5%), waiting 15min, scrubbing
* REALLY Hot Water
Sadly all websites about this topic are mostly AI-generated and have no true information.
Is there any chemical or method that I missed that would remove these stains? Any help would be appriciated.
