Topic: Polarizers in Brickfilming?

I recently had some issues with the reflectiveness of lego bricks, and got the idea of using polarizers to reduce non-wanted reflections.

Here is an image to show the effect of a polarizer:

Has anyone already tried this out, if you have polarizers can you test how it affects the reflections on plastic bricks?
Thinking about buying some but obv I don't want to throw money out of the window if somebody already tested it and it didn't work.
