Spots/marks on tin lining of Baumalu pot
My husband uses his Baumalu pot ever day and is fanatic about cleaning it with copper polish. However, he can't figure out what to do about marks on the tin lining. There are some small dots that I believe are due to minerals in water -- and there is a ring around the inside of the pot at the water level (he heats water in it every day to cook his breakfast -- he loves copper because it heats so quickly).
Does anyone know how to get rid of the rings and spots?
Thanks in advance.
