Difference between medical alcohol wipes, and those of the electronics industry
View attachment 153646
Alcohol swabs are neat (each in its own foil packet), convenient to carry in the pocket of your case (about 1.5 inch square), cheap (about 2 cents each), and do a great job
without water (no worries about warping or raising the grain, and your shaft is dry in a few seconds).

I agree that the "swab" or "wipe" style of packaging is great -- very convenient!
However, I need to caution you that the very product you show in the image -- of alcohol wipes used for medical reasons (prepping the skin for an injection) -- is
NOT "without water" as you say above. Medical skin-prepping wipes are soaked with rubbing alcohol, which is a 70%/30% formulation (70% alcohol, 30% distilled water). If you read the detailed liner of the box (or it may also be shown on the wipes foil package), you'll see this.
A better "alcohol wipes" product is one that is used for electronics, which by definition, cannot have water in it. Here's the product I like to use:
This product is 100% IPA (isopropyl alcohol), and is formulated this way so as to act as what we want the alcohol to be -- a solvent. When alcohol is cut with water, it's no longer a solvent, but an anti-septic instead. That is, unless, the dirt/impurities which the alcohol is intended to clean is also water soluble. With this product, there's no issue with water, because it has none.
Granted, this product might be a little on the expensive side, but it's guaranteed pure anhydrous alcohol -- mandatory in the electronics industry, because 1.) water and electronics don't mix; and 2.) in order to cut soldering flux and TV Tuner spray, the alcohol has to be anhydrous for its solvent ability.
When I use this product with the Magic Eraser, I don't get the "hairiness" that other folks mention, because there's no water in the alcohol to swell and lift the tiny fibers of the wood.
Hope this is helpful!
