I tried dissolving the solder mask already but acetone simply cleans it.
Ah so ...
The doomsday prophets where wrong, there will not be only cockroaches left.
There will be cockroaches sheltering under thin films of Amazon Kindle solder mask.

Bring out the MEK.
Just try not to melt the SoC with it.

Seriously -
Use a hypodermic syringe with a very fine needle to put a drop just where you want to scrub (with a q-tip?).
Your sources would be an animal feed store or a human pharmacy - just ask for u-100 syringes, they come in a pack of 10 - no prescription needed.
Be quick - expect the MEK to melt the disposable syringe nearly as fast as the solder mask.
