Cleaning the fridge and oven can become quite a horrible task even when using chemicals. Besides inhaling noxious gas, we also have to scrub hard to take the dirt off. Here is a tip which will make those tasks easier.
For your oven: Make a paste with 6 teaspoons of bicarbonate of soda with 2 teaspoons of water.
Apply the paste all over and leave to stand overnight. Using a soft damp cloth, wipe off the next day.
For your fridge: Add 1 teaspoon of bicarbonate of soda in 1 gallon of warm water and wipe all over and inside the fridge.
