The salt enables the smell of the lemon to broaden more distant, and the lemon itself will assimilate foul scents and microorganisms from the air. So when you get up toward the beginning of the day, the air will be perfect and your kitchen will smell normally new. You can utilize the subsequent lemon and salt wedges to clean wooden cutting sheets, as well. Since wood is permeable, it traps microorganisms in the grain. The lemon and salt will expel these bacterias with the goal that your cutting board is perfect and sanitized.
Ideally, since you know this simple hack, you can show your kitchen (and your wooden cutting loads up) some love, and leave it smelling perfect and new!
