Hmmm... are you sure? I'd be really careful. The brass work on most of the LV bags used to be brass plated or nickel plated steel, so unless something has changed I don't see why they would suddenly use solid brass on the belts. Besides brass is soft and has to be pretty thick to withstand the stress and strain of a belt tang. Mild steel is usually used and then the steel is plated to make it look pretty. Mind you Cartier use solid 18kt gold in the tongue buckle of their watch straps and 18kt gold isn't that strong so who knows? I would polish it very lightly over a small section first. I understand how you feel. I've just purchased a well used vintage LV bag from one of the on-line reputable vintage stores and from the photos the buckle part of the bag really lets it down. The bag looks great but the tarnished metal work sort of spoils the effect. I think this is a case of where LV could really improve the plating of their metal work as their product are not exactly cheap. Of course if the products kept on looking brand new all the time then we might lose the urge to keep on repurchasing new products.OMG, I am going to try it! I think it's brass and not brass plated..
The exact same thing happened to my LV belt. It got scratched by my kitchen granite work top as I was standing against it. I visited so many forums where people say a polish will work. Well it didn’t. I then took batters into my own hands. I lightly bugged it with a brasso pad then I sprayed it with Rust Oleum metallic gold spray. See the before and after photos and now it looks brand new! Good luck with yours.
I bought an LV belt a week ago, and it already has a ton of scratches that look horrible. How do you buff them off to look shiny and scratch free?
Any metal creams/polish?
