Although I love Kingsford charcoal for my grilling activities, I also learned another way to enjoy charcoal. About 8 years ago I moved into a fairy new house complete with appliances, slightly used. For some reason the refrigerator had an terribly obnoxious smell that I couldn't identify or find anything it could be coming from. I tried absoltely every cleaner somone suggested to me.  I took the back panel off and searched everywhere to no avail. I heard somewhere that charcoal would take out odors, but was skeptical about this odor. I tried putting charcoal in and into the bottom of my refrigerator and the smell went away...Thanks Kingsford!!
