When you touch it with your hand, it will feel the grip. This means that it will effectively collect dust and dirt.
It will "absorb" the spill, not just push it to the surface.
Leave the towel in the sun and stretch it to make sure it is thick. If you can really see through it as easily as the coarse cotton cloth, it is not a thick microfiber towel and may not absorb well or last for a long time.
Make sure your towel is an 80/20 or 70/30 polyester/polyamide blend. These are the most popular blend products for those who use superfine fibers professionally.
