聽講體質較燥底嘅人係好易戴到純銀首飾變黑. 而我就係呢類人. D 手鍊頸鍊每次戴幾日就變到黑媽媽, 用抹銀布捽捽捽, 捽到手指痛埋, 有時d 窿窿罅罅位仲要點抹都抹唔到. 實在太懶, 搞到有一炸戴黑晒嘅鍊擺左好耐都冇再戴. 直至有日朋友fb share左以下呢個方法,
1 tablespoon salt
1 tablespoon baking soda
1 tablespoon dish detergent
1 cup water
1 piece aluminum foil
Directions:
1. Heat water in the microwave for 1 or 2 minutes.
2. Cut a piece of aluminum foil that roughly covers the bottom of a small bowl (like a cereal bowl).
3. Pour hot water into bowl. Place salt, soda, and dish-washing liquid into bowl. Place jewelry on top of foil and let it sit for 5 to 10 minutes. Rinse jewelry in cool water and dry jewelry completely with soft cloth. Discard solution after use and make a new batch next time.
4. According to wire-sculpture.com, "this works well for gold-filled, brass, German (nickel) silver, and sterling silver. I have even cleaned jewelry with freshwater pearls, shell cameos and mother of pearl with no problem.".

五分鐘d 鍊仔就bling bling 靚番晒!!! 有相為證:
Wow浸左幾分鐘上半part已經白番晒!(第二張相) 再浸埋下半part, 用水喉水沖一沖, 攞眼鏡布抹乾, 就新嘅一樣! (因為屋企黃燈嘅關係,影唔到真實效果咁白.)
然後就揾番晒d銀鍊出黎玩 (太耐冇戴,未洗前真係黑得好離譜!....)
不費吹灰之力d 鍊仔就bling一聲! 以後都唔洗捽到手指都起枕喇!!
然後我好無聊咁做左小小research. 呢個用baking soda solution 洗銀嘅方法, 大概原理係將銀上面嘅化合物(tarnish - 啡啡黑黑嗰d) 轉化番做純銀. 另外原來用抹銀布抛光, 其實係將嗰d化合物抹走, 過程中唔多唔少係會抹走d銀ga!!
