I have always had this small water stain on my montsouris and since my vachetta wasn't dark it was visible. I was at the store and saw the magic eraser and without a doubt in my mind I bought it and got home fast! I remembered Tink's thread about her vernis bucket and did exactly as she said! The Mr. Clean Magic eraser is now my new best friend!!!! The first wipe was tough because I was thinking man I just conditioned this. Well I reconditioned and the bag looks brand new!! I recommend this to anyone!!! THANKS TINK for you help!!! P.S I swear it made the vachetta lighter not that I mind dark vachetta Here are the results!
