The usual way is to use crossed polarizers. Put one in front of the light source, and another one that rotates in front of the lens. Rotate the lens polarizer until the specular reflections is minimized. It's much better to prevent the problem in the first place like this than to try to repair a poor image.

This is a very strange result that I first saw about a month ago on one person's system. It was find for everyone else's. The fix was to change the renderer for the figure. I don't remember what fixed it but it was something like going from OpenGl to zbuffer or painter or something.
set(gcf, 'renderer', 'zbuffer');
