I am making a cowboy hat cake and have the brim of the hat all dried, however there is powdered sugar on it that didn't absorb into the gumpaste and I don't know how to get it off. Any help would be very much appreciated!
You can quickly steam it. If you don't have a steamer you can hold it over a steaming tea kettle.
Brush it with a dry paint brush.
I have tried the dry paint brush and it didn't come off. So I will have to try to hold it over a steaming tea kettle and see what happens. What about brushing lemon juice or vodka over it?
I have tried using vodka, vanilla, or even a tad bit of water...it usually changes the look of it...melting the sugar and making it shiney. Id try the steam first.
