Ok I am making a gumpaste bow, one of the two-loop bows, for the top of a wedding cake due Friday. I ususally use Crisco instead of cornstarch when rolling out gumpaste or fondant simply because it has always worked better for me, but since it wasn't really working this morning, I tried cornstarch. Worked fine...no problems. The pieces are now drying and I'm wondering....how do I get the residue from the powder off the gumpaste? It's very dull in color right now because of the powdery residue. I tried to do a search but came up with nothing on this. I will be dusting the bow with red lustre dust once assembled and dry, but I really want it to be as bright red as possible...not this dull blah red right now.

Brushing with a small dry brush usually works. If not, try it slightly dampened. HTH

I tried brushing it with a dry brush. That got a lot of it, but there are still some spots where there was more cornstarch. Those spots just won't go away. I tried wet too. Didn't help. Now I have to wait for those spots to dry before I can try something else.

Try airbrushing it with vodka. That always works for me.

I'd love to, but I don't have an airbrush.
