how do you steam a large fondant cake and why other than a shine do people steam them, i was wondering if it would get rid of finger prints etc

I think some people use garment steamers to steam their cakes, it gives the fondant a shine and gets rid of all the leftover icing sugar or cornstarch residue left on the cake.

I don't think it will get rid of fingerprints but after covering the cake try smoothing it out with a fondant smoother or the palm of your hands, hopefully that will diminish any fingerprints that were left when working on the cake.

I bought a shark iron and use it just for cakes it has a steam button and it works great. 20 bucks

I LOVE my garmet steamer (not just for cakes) - and I think it's only $30 or $35 on amazon. Wonderful!
