I have this edge grain maple cutting board. I’m a new user and read around that I could take out onion smell from the board using baking soda paste. So I did that but left it overnight and when I cleaned it up it looked like this (and on top, it doesn’t seem the smell is gone). Before applying the baking soda paste, I do a previous treatment with vinegar. The top left corner of the image shows the original color then all got darker. After I left it drying for two days I’m now trying to sand it manually with 220 grit, but I don’t think is helping or at least not fast enough. Is there any hope to return this to its original beautiful maple color? Any advice on how to proceed?

It seems that US price is up now and looks like $1000 more than the base price of the 2025 version same model. It doesn’t even say how much RAM it has. Even though I would have loved the airflow redesign and the new more power efficient CPU, I’m glad that I got the 2025 on sale last year.
