White moldy substance on support stakes

[AngelinaMaria]

So here is my lowes rescue phal that I got a couple weeks ago. When I got it the leaves were wrinkled and limp. I watered it right away and a couple days later the leaves had perked up. A week ago I took it out of the pot and trimmed off a few rotted roots. There were a few good roots a couple inches long that looked good. I didn't have new potting media so I just loosened up the tightly packed moss it was in. One of the support stakes was kind of rotted at the point where it went into the moss so I threw it out and the moss that was immediately surrounding it. I replaced both stakes with a couple bamboo skewers I had. So today I just checked all my orchids and noticed this moldy looking stuff on the skewers where they go into the moss. Anybody know what it is? I just ordered some Phalaenopsis classic mix and clear pots from repotme last night. Is there anything I should do until I get the new mix and pots? Thanks in advance!
