No. I don’t rinse it or anything. I completely ignore it.

Teak, for whatever reason, is ideal for wet environments. I literally bought it put it in my shower 9+ years ago and that’s all.

I don’t leave items on it bc that pools the water & keeps it from running off & that will leave dark watermarks on the wood. So if nothing’s left on it the water evaporates evenly or runs off & it dries and stays nice looking.
