Scratches on glass top

I have some scratches on the top glass panel of direct stream. Are there any spare parts to replace it or there is any trick or process to remove them?

As I learned awhile back, it is actually not glass, but painted wood (MDF). Depending on how bad the scratches are, you can polish them out similar to how you would on a car finish.

I see. There is also a replacement spare part that costs around 40$ if polish is not enough
I will try polish first
