The neat and simple solution is indeed a laser. However I have seen other quirky ways to denote a build revision. These include a resistor with a value marking that matches the build revision e.g a 1K marked 102 could indicate assembly 1.02. Another

I agree with the two other replies. Left alone, it is a defect. If it's just excess adhesive or coating, you can use IPC-7711/7721 'Rework, Modification and Repair of Electronic Assemblies' for guidance on removing. Section 2.3.1 explains how to te
