Suede is a type of leather with a "napped" finish. Suede is used to make all kinds of things, including shoes and sandals. When you wear suede sandals you want to be careful. Suede becomes dirty much more easily than other fabrics. It is also very susceptible to scuff marks. If your suede sandals do become dirty, you can give them a good cleaning.
Brush your sandals with a suede brush. This brush is designed to lift up the nap and help remove the appearance of scuff marks. If your sandals are muddy, you need to wait for the mud to dry. Then brush with the suede brush. Just remember to keep all of your strokes in the same direction.
Use a pencil eraser on any marks that you may have on your sandals. Just rub the eraser back and forth until you no longer see any marks.
Scrape a sharp knife across the worn part of the sandal in the same direction each time. This will lift the nap back up.
Put a little vinegar on a paper towel and work it back and forth over any liquid stains that you may have on your suede sandals. Allow the suede to dry and then use your brush.
