Ugg Tasman slippers mustard seed women size 8 discontinued

Pre owned in good structural shape. There is some matting on the inside fur. Right when I bought them from the website, I used 3 rounds of Crep to waterproof the suede, so the tops and sides are very clean. The midsoles are what have gotten dirty. Maybe a suede eraser would take the marks off? Still plenty of life left and a hard to find color.
