old shoes need cleaning

hi all, used to ride a while ago but back problems put me out for a good 2yr, now going to a mates to service my bike and replace the brake ppads on wednesday before we go for a ride. going through my gear i got my shoe out but there got a bit of mould on the outside from sitting in the bottom of the wardrobe, any ideas on the best way to clean them and what to treat them with- the materials suede. thanks in advance.
