Hi guys,
Found this motherboard in the wild and sadly the battery leaked. I removed the PLCC CPU socket because the contacts were corroded and broken; ordered a new one. I used vinegar to neutralize the battery juice.
Traces in the area have a brownish color. Do i need to remove the remaining components and clean the solder mask, tin the traces? Or does it look good to you?

First sand them with a extra fine sand paper (180-220) and then tin them with desoldering wick.

I´s suggest a fine glass fiber pen for removing the corrosion and sclerotic solder resist mask.
Then tin the traces with a good(!) flux and no wick. The traces have already become thinner due to the corrosion and cleaning, so a regular tinning in it´s "natural" thickness is an improvement and desired here.
