These synthetic drying towels are awesome, the amount of water it's able to absorb is pure magic. These towels leave no water residue behind. Make sure to leave it a little wet when you store it in the container that it came with. Even if the towel dries, you can just run it under water and it will go back to normal. Now my family only dries our cars with these towels, you don't have to worry about scratching your car with these synthetic towels.
