Sarah Lentz: "Ok, I just tried this and it seriously did work. I did it twice on a burner that's had scorch marks for a year or more and they're gone! For anyone as OCD about cleaning as I am, this is a must! I would be prepared to do it at least twice, more if you've got bad burns. This really works!!!"
DIY Fabric Whitener It is SO simple and can’t believe that it works. You take one cup of cream of tartar (used in baking for some frosting to make them white, so that’s why this makes so much sense) and three cups of water. Mix together in a clean bucket and let your-at one time white shirts- soak and enjoy a fresh white shirt after washing in a regular cycle.
-Gather all of the clothes you want whitened (make sure they are sturdy and not delicate fabrics and that they don't have any colors at all, threads, etc.) -Throw them in the washer on HOT and wait until it has been filled with water- then STOP the washer -Add (believe it or not) 4-5 cups of bleach -Allow to soak for a few hours -Add laundry detergent and wash
