The detergent just loosened the retention of the water molecules. Surface tension is what you see when you see water in a glass mounded up slightly or a bead of water on a stained deck. Add a little detergent and it breaks down the surface tension. Thus the water soaks in faster. When I was a Volunteer Fire fighter and we had brush or forest fires we would add a little detergent to the Fire Engine water tank. The water would then soak into the ground much faster to put out burning of roots and buried material. The same process for your Hydrogen releasing to burn. Probably another reason they tell you to keep flame away from charging batteries that are bubbling off hydrogen gas. Now some smarter cookie than I can come along and correct my little spiel here.
