I've never done this before and am not sure about something. What can I use to clean the mirror that will be food safe once it dries? I don't want to clean it with something and then make everyone sick. TIA!!!

I would think vinegar and water should work

I'd make sure whatever I'm serving on a mirror is on its own board or in its own wrapper. (If it's a cake, you wouldn't want it cut directly on a mirror to avoid cut marks and scratches.)

Ok, thanks guys! I didn't even think about scratching the mirror!

I did a large cake last week for a birthday and I had it on a cake drum and then the cake sat on a mirror. I looked very elegant and reflected all the bling. You don't want to scratch the mirror so it should be on something so as not to.

Also, most mirrors are on the thin side. You can't lift a cake on a mirror unless it's a very small cake. Mirrors are not constructed to take the weight. I've used a mirror, but the cake was on a drum as cakegrandma said.

Mirrors are a beautiful way to display and present a cake. I use a plywood sheet cut exactly to fit the mirror and wipe down the mirror with vinegar water. The cake is always on a cardboard or plastic base.
