A solution that is chemical-free, halves scrubbing time and let’s you keep your pan.
You will need:
1 cup of vinegar
2 tablespoons of baking soda
1 cup of water (give or take depending on the size of your pan)
Step 1: Fill the bottom of the pan with a layer of water.
Step 2: Add the vinegar.
Step 3: Bring the pan to the boil. It should be looking a bit cleaner already.
Step 4: Remove the pan from the heat and add the baking soda. Expect fizz!
Step 5: Empty the pan and scour as normal, if necessary add an extra bit of dry baking soda.
Step 6: If there are any super stubborn marks that don’t come off with scouring, make a paste of baking soda and a couple of drops of water. Leave the paste on the marks for a while and return to clean as normal.
