Before she spends any money, tell her to try scouring it with BAKING SODA. It's the most effective cleaner I've found. It's non-toxic, cheap, non-abrasive, you have it on hand, it's anti-bacterial--and most important, it works better than most of those expensive things. I've even gotten grape juice and kool-aid stains out of white formica with it. It works great on those little brown/black speckles on the bottom of skillets. It removes goo left from stickers. Takes out gray marks left by metal utensils on the coated cast iron. I buy it in big boxes, and don't even keep other scouring products on hand
