Walls get very dirty you know by scuff marks from the shoes, or kids writing on the walls. The best thing that I have found is a magic eraser, you can buy it at any store and it comes off very easy. You start off by getting it wet, ringing it out, making sure there’s no excess water and then just kind of rub. You might have to, you know, apply a little bit of pressure but it does come off pretty easy. After awhile the magic eraser kind of dissolves so you don’t really have to, you know, rewash it or anything like that it just dissolves and then whenever you’re done just throw it away.
