ABSOLUTELY perfect product for brass. I had bought the home in Villedieu stoves in product Mauviel pot a kilo ............ he lasted 10 years! in the end, (I'm using it not every day!) it was moldy half, I threw it and bought it in smaller quantities .And yet my kitchen is full of copper but ... ............... must polish and that's beard, once every 3 months is, for me, enough! with this product even in the kitchen, if you do not do that sprouts oxide, they are almost clean,
