I have a buttercream cake that has a fondant border and royal icing stenciling that is painted with a luster dust. Will steaming the fondant to get the powdered sugar off and make it shiny hurt the royal icing?

I would only be steaming for a few seconds all the way around the cake, but I am afraid that the water will break down the royal or cause the luster paint to run.  Has anyone tried it?

TIA!

you can't steam if before you stencil it? 

i've never done this--on one hand i think like you do it will run my work--eeghads!

on the other if done lightly--it might really set it off--if the paint was super dry--i had some not dry for a couple days recently--

all that to say--make a bit of this in advance and test it --and tell me how it went please--unless someone smart knows the answer in the meantime--

luster paint never ran on flowers that i steamed...it might work

Thanks memphisk8.

I had already completed the cake and was getting ready to take pictures when I decided that steam might make the ribbon look better.

I decided to give it a try, starting at the back of the cake. It didn't hurt the royal icing or the painted on luster, but I didn't let the steam hit the cake for long. In fact, I didn't really get the fondant to shine up like it normally does. I probably needed to let the steam hit it longer but I was afraid to.

Next time I will either steam before stenciling or practice on some parchment first.

Thanks for your input.
