I have a sword, custom built (not terribly expensive, chinese forged steel, but I love it), for iaido, and, having forgotten to clean it last time I used it, I noticed a little bit of rust on the blade. I went to a shop and asked for a product that removed rust. I got HG (Hagesan) rust remover. I was told it would not damage the steel. I cleaned the sword with it and left the product on for about 10 minutes (the flask said "leave on for anywhere between 10 minutes and a few days), then rinsed as it said on the flask and now the blade has turned blackish/rainbowy. The flask says the product contains phosphoric acid. How do I fix this?
