The girls in my daughterâ€™s group all recently received their grips. My daughter and a teammate have had a couple private lessons together and that coach has let them use them a little to break them in. Well yesterday the bar coach let all the girls use their grips for the first time. She took a spray bottle and wet all the girlâ€™s grips (except my ddâ€™s). I know the manufacturer said not to use water as it weakens the leather and voids the warranty. I was glad that my ddâ€™s grips were not sprayed. However, she saw it as the coach treating her different, maybe in an attempt to hold her back. I told her it was because her grips were already broke in. Our gym has a water bottle hanging at all the chalk stations. My son says the boys do not put water on their grips. Some of the momâ€™s are upset that the coach has wet the grips. Is it common practice to go against manufacturersâ€™ recommendations and wet the grips?
