Oh dear, I need some help. DD came home from nursery yesterday with her soft-soled leather baby shoes covered in a dried on mixture of cornflour and water. Apparently they were playing with cornflour and she has clearly walked around in it and it has dried to a thick shiny gunky flim on the suede soles. This means she can't wear the shoes as she slips over because there is no longer any grip.
DD (18 mths) is walking but we can't yet convince her to wear any other shoes than these so I'm really stuck! They are Robeez shoes (like this).
I have tried scraping and scrubbing with a stiff brush but it's not moving. Help!
