Empty and clean your fridge
Start by removing the food and cleaning the surfaces with a mixture of warm water and white vinegar. This will give you a clean start.
Take a small open container
A dish, small bowl or ramekin will do the trick.
Add the sodium bicarbonate
Pour around 2 to 3 tablespoons of sodium bicarbonate into the container.
Place the container in the fridge
Place it in a stable corner, preferably on a middle shelf for even absorption.
Leave to work continuously
Baking soda absorbs unpleasant odours naturally and discreetly. It is effective for about a month.
Renew regularly
Remember to replace the bicarbonate every 4 to 6 weeks to maintain its effectiveness.
