Baking Soda + White Vinegar I have a big box of plastic goldtone buttons that has been sitting around for a long time without being touched. The reason is their colour: even though I love their designs, the plastic goldtone makes them look horrible and cheap. I keep opening the box and looking through it, but I just can't force myself to use them in any of my projects. It was time to do something about it. I was planning to get rid of them but before that I wanted to try one of my chemical experiments on them...nothing would be lost anyway if it turned out to be a useless plan!
I went for a mix of hot water, vinegar and baking soda. I let the buttons soak overnight and lo and behold... my ugly plastic ducks had turned into pretty vintage looking swans ! I don't know how I came up with this idea, but I use these " ingredients" for cleaning and I thought it might have a discolouring effect on plastic, and so it did.
