Raising timber grain

How many here use water to raise the grain on a cutting board?

I've never done it before but on the last one I made (long grain), the was a fuzzy patch after wiping it. I've just made another (long grain) for a friend and had a go at wiping it down with a wet rag and sanding back to 220g before applying mineral oil.

I use denatured alcohol. What kind of finish do I see in the last picture?

Had to google that one - mostly sure it's methylated spirits over here. I still haven't quite worked out what mineral spirits is - I think that one is mineral turpentine. 

Is there a difference between using denatured alcohol and water? I've put on a coat of mineral oil. I rub it in and let some sit on top overnight before rubbing in a few more coats.

Yes there is a difference between denatured alcohol (DNA) and water. I've read any times that DNA will raise the grain but in practice it doesn't work for me. I run my cutting boards under the faucet at the kitchen sink and let them dry over night before finish sanding. If I'm in a rush i'll sometimes dry in the oven set to 150F but that makes me nervous that I'll get some un even drying.

I'm with Drew, alcohol doesn't do much to raise the grain. Friend of mine had been using it, but ran out and used water instead on a recent project. Says the difference is astounding.

I usually just wipe the surface with a wet rag, or occasionally spritz with a spray bottle. It doesn't take much.

@lewisc Denatured alcohol is the solvent in shellac. Also called ethel alcohol or ethenol. Basically grain alcohol, think 180 proof, with an additive to make it undrinkable.

I suppose if it were mixed with water it might raise the grain better. I only use it as a cleaner or solvent.

I'm becoming a fan of using water on all projects. Rough sand, wet and let dry at least a couple of hours. Sand to 150 and wet again. I've heard of sanding to 180 and wetting again before going to 220. I believe wetting two times is plenty so I stop wetting at 150. I alwayssand to at least 220.

Wetting has two major advantages. Raising the grain gives you a smoother finish and while the project is wet you can see any glue spots or scratches. The second wetting verifies that you fixed the blemishes.
