Hi all - just a random question. I found that if I touch my echeveria I leave finger prints or end up wiping off that waxy, powdery surface from the plant's leaves. So of course now I try to be careful if I have to touch them to not touch the leaves, but I was wondering - is there a way to get that powdery finish back on the leaves? Or is it just gone once it's gone?

Here's a pic of some really pretty echeveria my neighbor gave me, but I think in the process of removing them we touched them a lot and therefore a lot of the leaves have fingerprints all over them.
