Make a white purse white again!

I almost never buy lighter colored purses, but I saw a really cute off white one at target one day and bought it.  

So far I haven't regretted buying it, but lately it's been looking a little gray from all the dirt and dust it's endured.  I tried to wipe it clean with water and a washcloth, but didn't have much luck.  

Today I remembered that I had some Mr. Clean Magic Erasers under the sink.  I used one on my purse and it was like "magic" ;).  My purse is dirty no more and looks cleverly clean!
