To deep clean pans, soak the pans in some warm soapy water for 15 minutes to 30 minutes.
Then take a soft bristled brush or a non abrasive sponge and scrub the pan until clean.
You can also sprinkle some baking soda into the pan and then pour some vinegar into the pan or even on the bottom of the pan and allow it to fizz for awhile.
Then after it sits and fizzes for at least 10 to 15 minutes you can scrub and rinse the pan.
You can also create a paste of baking soda and water and place it in the pan and let it sit and then scrub and rinse the pan.
The use of vinegar when cleaning pans is a good and natural way of getting your pans clean without leaving any soapy taste to the pans like some soaps can.
You can also sprinkle some baking soda into the pan and then pour some vinegar into the pan on the baking soda and allow it to fizz and then scrub the pan clean.
The baking soda and vinegar will help to lift off any grease, oil and other food residue from the pan and make it easier to clean the pan.
If the grease, food debris etc are stubborn you can fill your sink with some warm or hot water and add some baking soda and vinegar to the sink water.
Then allow the pan to soak in the sink with the baking soda and vinegar for 30 minutes to a few hours.
Then empty the sink and rinse the baking soda and vinegar off the pan and scrub it clean.
For really stubborn grime on the pan you may need to use a good dish detergent such as Dawn dish detergent or a degreaser.
