Newb question - got water on oncidium and it turned brown.

[dr_orchid_lady]

Just got into orchids. I can't find a good anatomy reference for the smaller parts so excuse my lack of terminology.
I water my orchids in my kitchen sink and try not to get water on the leaves/stem. However, some got on one of the leaves that sprout out of the side of one of the pseudobulbs of my Sharry Baby. I put it in front of a fan for awhile as Miss Orchid Girl says. However, the base of this "folded leaf" part and the structure below turned brown. The leaf itself just fell off today. The pseudobulb the structure-with-leaf juts out from looks fine.

What can I do differently? I feel like no matter how I try some water is going to get places.

Side question - what about when the ridges below the pseudobulbs look a bit dry and flaky, but the plant itself is hydrated. Is this normal?
