Dip-It Compliment - Stain Remover
Anyone have a coffee pot that looks like it hasn't been cleaned since Hoover's administration? How about a teapot or a thermos? All clean, but stained. We can pour in some Clorox or whatever else is around but they are still stained. This product is also advertised as being excellent for food and beverage stains in casserole dishes, cookware and porcelain sinks but I can't vouch for that since I've not used it for that purpose.
There are two products under the name of Dip-It. A liquid for drip coffee makers and the powder for the others. You have to look around for the powder. It's in a very small box, looks a bit like dishwashing powder, but it does the trick no kidding. Give it a try. Many times it's available next to the coffee selection in your grocery. It's worth the search.
