Suede is a complicated material. It is rather difficult to make these shoes clean because suede does not like water. Most shoes can be cleaned with water and soap. However, suede is more difficult. One way to clean them is to use a shoe brush and eraser. Using these will remove marks that have been made on the suede shoes. Another way is to use water, but only a light amount of water. Use a slightly wet rag and rub it over the shoes.
Put something inside the shoe so that the flap stay open. Then let the shoes dry for a long period of time. Then use the suede brush. Sometimes suede shoes can get stains on them. It depends on the type of stain to determine what should be used.
