Roughness and darkening on the cutting board surface are inevitable for continued use. Although I am concerned about the appearance and hygiene, it is not harmful to practical use, so I tend to keep pretending not to see it. I'm not sure when to throw it away.
I would like to introduce to such a person the "cutting board shaving" of the 100-yen shop Daiso. It is an item that scrapes off the roughness and dirt of the cutting board.
Daiso "cutting board"
Easy to use. All you have to do is rub the cutting board with water. If you have a basin that fits a cutting board, you can immerse it in the work. It saves water.
As you continue rubbing, wood chips will appear on the cutting board surface and cutting board. Proceed while flushing with water as appropriate. It is easy to scrape the heavily soiled part by rubbing it in a circular motion.
Rub only the left half for about 5 minutes and let it dry as you can see.
The rubbed part regains the original bright color of the wood, and the deep knives remain, but it has become much less noticeable. Even more to the touch!
To be honest, the shock of "Is it so dirty?" Is greater than the joy of "Being beautiful!", But I am very satisfied with the resurrection of the cutting board that I thought it was time to throw it away. It is made of both wood and plastic, so please use it for your favorite cutting board maintenance!
