Another tip from Grandparents.com
Still scrubbing that roasting pan's burnt bits from last night's dinner? Reach for the baking soda and get your life back.
Simply take about a quarter cup of your favorite dish detergent (powder or liquid) and mix it with a quarter cup of baking soda. Spread the mixture on the bottom of the pan, then fill it with hot water and let it soak overnight. Dump out the water in the morning, wash as normal and you have yourself a clean pan!
