Black residue
Black residue
It seems you're referring to a white substance and are wondering how to remove or clean it. Could you provide more details about its appearance, location, and any surrounding context?
The initial method to address it would likely be using compressed air. Regarding its nature, I'm uncertain. I've observed similar corrosion on capacitors in older systems from around 2005—usually appearing as clumps near the base or along edges. This spread pattern has settled into the heatsink, suggesting it isn't firmly attached.
Could it really be salt? I wasn't very focused on science, but I learned that heat can lead to salt formation in certain chemical processes.
Have you tried it? People seem to be in agreement, but I’m not suggesting anyone actually does this.
From my perspective, salts are used in making capacitors. These devices include electrolytes. They aren’t what plants need, but the liquid inside does contain salt. It’s conceivable that bad capacitors might release salts when they malfunction. The salt isn’t generated by heat—it’s already present within the capacitors from the start. Still, I doubt it comes from a defective unit since the ones shown appear intact.
Not really! I didn't mean to say it was salt, not the NaCl kind.
