I only mentioned the toothpaste because I saw a video on it, but since I've never personally tried it, so I can't say how good it "really" works. Anyway, there's like a gazillion YouTube videos using Toothpaste. Sure you can go spend More Money, but I hope everybody already has toothpaste so five minutes of your time doesn't seem like a big deal. Here's a sample from YouTube.
