I have a collectable ninja sword that I've had for four years, and I really like it, but for some reason it has a few scratches on it, and it keeps on getting more and more scratches every year. I don't get it out that much, but for some reason it just keeps on getting scratches. And I've tried to wash it of with water, but it didn't do any good. And I saw a rust spot on the handle it. I'm just a little worried that it'll look really crappy after a few years and that it'll have to be thrown away. Am I doing anything wrong? are there any products or other things I can use to clean it? It's entirely made of metal, and doesn't have a wooden handle covered in string, but do I need something to properly clean it?
Thanks!
