Extending the life of skin electrode pads
For electrodes please remember, pads like to be sealed as they can dry off in 2 weeks time of careless storage. If too dry and come off the skin - drop a bit of water on the jelly surface and allow the gel to absorb it. The gel used to dry off and become less sticky. On the other hand, after sweat absorption gel becomes bulky and falls out from skin. The sensible moisture management can considerably increase the life of your typical hydro-gel pads for TENS/NMS/EMG.
Avoid fat surfaces
Try to avoid grease on skin: any fat residue such as creams, oily skin should be cleaned with alcohol-based wipes or baby wipes. Remember that fat residue permanently decreases the skin pads adhesion to skin.
