This is a carry-over from the "What I use to fill my iron with water " thread.
Have you ever tried to refill one of those small hand sanitizer bottles from a larger (squirt) bottle? Messy is an understatement! What we use is an 8 - 12 ounce bottle that has a wide opening but a thin squirt nozzle that fits into the neck of the small sanitizer bottle. (Many of you mentioned using this type of thin nozzle bottles in the previous thread.)
First, fill this 8-12ouncer from the large hand sanitizer, which should be relatively simple because of the wide opening. Then, use the filled 8-12ouncer to fill the small sanitizer bottle. Works like a charm and, best yet, saves money along with making a small sample sized sanitizer always available.
