Do I need to re-sand after cleaning wood?

Am getting ready to apply Penofin to an outdoor wooden table that I've sanded down to 180. The guy at the hardware store said that after I washed it with a wet rag, some imperfections would come to the surface and it would be a good idea to sand again with the 180 (he said he repeats this process 3 times).

Well, he was right about the first part... I used a wet tshirt to wipe off all the sanding dust, and the wood when dry does seem a little rougher (less smooth) than when I had just finished sanding.

Is the re-sanding really necessary? I don't mind the wood not being perfectly smooth, I just don't want to risk the Penofin not applying properly.

Just hit lightly again with sandpaper and don't wipe it with water after this time. Just blow or vacuum off the dust, or wipe with mineral spirits. Water will raise the grain every time.

That bowl was perfect right up until that last cut...

I wouldn't use water at all. Sand with 180x, and brush off/blow off/vacuum off dust. Do that in an area away from where you will be finishing. If the wood needs to be wiped, use mineral spirits. Allow the wood to dry completely before application of Penofin.
