I have made the loops for a bow out of a deep royal blue MMF and would like
to know what the secret is to cleaning up the excess cornstarch/sugar powder on the dried fondant. What is the best way to accomplish this?

Thanks,

If they're dry you can rub it off with a paper towel tha has a little vodka on it. You can also just take a pastry brush and brush most of it off. The vodka works really well, though.

I've used a little vodka and a artist's paint brush (smaller than a pastery brush). Dry brush first then lightly with a dampened brush. I tried the paper towel once and I guess I had too much vodka because I ended up with a bit of a sticky mess with paper towel stuck to my fondant.

I use a vinyl mat and a tiny bit of shortning to roll out fondant instead of using cornstarch or p/s for that reason. No dusty spots, and the fondant stays nice and supple. (doesn't help now, but for future projects!)

Thanks for the advice. I managed to get the sugar spots off of the fondant by brushing on a light application of pearl glaze. I will try the vodka next time!
