Hi. I'm Rachel Yatuzis, and I'm going to show you how to remove rust build up from your sink. A great way to clean any kind of metal, is to grab some lemon juice and baking soda. If you don't have a lemon around, or lemon juice,you can substitute that with vinegar. Make a paste out of these two ingredients.And this paste, is going to be your metal cleaner. Environmentally friendly, it's non toxic, and usually everybody has these ingredients around their house. Dampen your sponge, or dip it into the paste after you got it a little bit wet. And, just rub it onto any of the areas that may have a little bit of rust on them. Sometimes you can just wipe the paste off and you'll have a clean area. If you have more stubborn spots, you wan to let that paste sit on your sink for fifteen, thirty minutes, and then wipe it clean with a damp sponge, or a damp cloth. If you've got detailing in your sink, maybe around the faucet, you want to get some catchup, and you can use a q-tip, or you know, you can use your finger, anything to apply it, to the little tiny detail areas that are hard to get to. Let the catchup dry, and then wipe it clean. Wipe it away with a damp sponge. I am Rachel Yatuzis, and that is how you remove rust stains from your sink.
