Wrist strap with dry skin

currently we have ESD lotion for the techs with dry skin, lately the Techs have been using DI water to stop the monitor from going off.

what is your opinion on this? you see anything wrong with the Techs using this technique?

If the contact resistance is measured, then it works. The question would be if the DI water dries up, does the contact resistance go up or will the wrist strap still make good contact.
