What You'll Need:
1 cup vinegar

你需要：
1杯醋
1/2杯小苏打
1大汤匙盐
1大汤匙双氧水

Directions:
用法说明：

1.Most think sweat stains are caused by sweat, but they are actually the result of a reaction between aluminum-based antiperspirants and your body. To attack the discoloration, soak the shirt in a bowl filled with the vinegar and two cups warm water. Soak for at least 20 minutes.
1.大多数人认为汗渍是由出汗导致的，但事实上是含铝的止汗剂和你的身体之间发生反应的结果。想要去除这种污渍，把衬衣浸泡在盆里，加入醋和两杯温水。至少浸泡20分钟。

2.Mix together the baking soda, salt, and hydrogen peroxide until it forms a paste. Remove the shirt from the vinegar water and gently squeeze until the shirt is just damp. Lay flat on a towel-covered work surface and coat the stains with the mixture. Hydrogen peroxide is a natural whitening agent, and baking soda and salt work together to lift the stain. Let sit for at least 20 minutes.
2.把小苏打、盐和双氧水混合搅拌，直至糊状。把衬衣从加了醋的水中取出，轻轻拧干直至不滴水。把衬衣平摊在一个铺了毛巾的平面上，用之前搅拌的混合物覆盖污渍。双氧水是天然的增白剂，和小苏打、盐一起可以去除污渍。坐等至少20分钟。

3.Toss the shirt in the laundry with a load of whites and wash. Voilà! Now you can take off your jacket and raise your arms proudly without worrying about flashing nasty stains.
3.把这件衬衣和其他衣物一起拿去洗衣房清洗。瞧！现在你可以脱下你的夹克，骄傲地抬起双臂，而无需担心那些显眼的难堪污渍了。
