Olgita, hello there! Yes, I did wet the eraser. I used the magic eraser for the very first time (and only time) when I got color transfer on my Boy. I'm not a pro at this, but this is what I did. I put the Kate Spade Leather Conditioner on it first to see if the transfer would rub off. It did not. Then I took a corner of the Magic Eraser and wet it with water and squeezed out the excess water since I did not want to create a water stain on my Bag.. I gently rubbed the spot with the eraser for about 4 seconds and it was gone. HOWEVER on one of the ridges (the frame that goes around the Boy bag) ended up getting a teeny scuff from the eraser. It almost looks like a teeny dirt smear. It is barely there. Maybe the edge is more fragile.
Thank you so much for your help for the water repellent! ♥️
