Ingredients:
- 1/4 cup baking soda
- 5 drops essential oil of your choice
- juice of half a lemon
Sprinkle baking soda on the stain, then add drops of essential oil and sprinkle with lemon juice. Let sit over night or several hours. Wipe baking soda away and then rinse well.
If the stain is on the side of the sink, make a thick paste from the ingredients, using more baking soda if necessary. Make sure the paste sticks to the side of the sink.
