Thank you for the replies, I will give it a try with water..
Just regular tap water ok?
The sand paper wont push the grain back down?
I am concerned about getting rust spots (speckles), and couldn't find brass wool, so are the scotch bright pads ok?

Good questions.
The following are my answers, and may not agree with some of the other folks. They are based on experience though.
Plain old tap water will work just fine. In fact, some of the better stains are alcohol instead of water based simply because alcohol does not raise the grain very well.
Yes, if you use too fine of sandpaper, it will just mash the little raised whiskers back down where they came from. The trick here is to use a sandpaper that is course and sharp enough to cut off the whiskers. I've found that the red "garnet" paper in 220 grit works very well.
When the grain is raised, you will notice that if you gently rub the wood in one direction it is very rough. If it is rubbed in the other direction it is slightly bumpy, but it doesn't try to "grab" your fingers with its whiskers.
Using brand new 220 grit sandpaper after the surface of the wood is dry,
gently sand in the direction that was very rough. That will allow the paper to cut off the whiskers without pushing them back down into the wood.
The idea here is to cut off the whiskers, not to remove any surface wood, so go easy with this.
After sanding, repeat the wetting, drying and sanding process. After 2 (and sometimes 3) sandings, you will find that wetting the wood will produce few if any new whiskers.
If there is any chance that you are going to use a water or alcohol based stain after whiskering,
do not use steel wool.
Steel wool is notorious for leaving bits of itself in the open pores of the wood, and these will create thousands of little rust spots on the wood when the water wets them. Some of the alcohol stains also contain some water and it too will cause the steel wool fibers to rust.
If you are not going to stain the wood, or if you are going to use one of those oil based stains that I detest, the steel wool will not cause any problems.
Have fun!
