First off i wanna say Thank you lifehacker~! what would i do without you :)

and here’s a tip  on how to Clean Tarnished Silver with Aluminum Foil and Baking Soda

and seriously, who wouldn’t like things like this anyway.. here’s the write up of it :)

enjoy :)

Dunvi gives us an easy way to remove tarnish from silver with the power of science:

The way jewelery shops and normal people remove tarnish (Ag2S) from silver is by taking silver polish (an abrasive) and pretty much scraping it off. Alternatively, they may use a solution of HCl to do something, which involves removing the layer of tarnish. Unfortunately, this means that you’re removing material, and for thin or very precious objects (such as earrings, lockets, etc.) they’ll flat out refuse to help you… or possibly try and end up just destroying it (I know this how?).

Well, my chem teacher had a different suggestion. She said to take a sheet of aluminum foil, spread a baking soda solution on top, and then place the tarnished surface on top, and voila!

The way this works is, aluminum is above silver in the activity series. The baking soda solution creates an electrically neutral environment (I think this is what she said about the baking soda, anyway) for the ions to move in, which allows the silver and the aluminum to do that fancy electron swap thing you might remember as oil rig from chem 101. Anyway, the result is that the sulfide ditches that silly silver (presumably to go and hang out with the obviously much cooler aluminum instead) and leaves you with nice silver fancy things – with all the silver still there!

I haven’t actually tested this myself yet, (since while I do have tarnished silver, I don’t have aluminum foil or baking soda), but a really, really fast Google search suggests I’m not pulling this out nowhere.

according to this “presumably to go and hang out with the obviously much cooler aluminum instead”

i guess it’s much cooler to be aluminum hahah

awesome~!
