Disinfecting Metal Snap Electrodes Possible?
Hello, a few years ago I had asked if cleaning the AgCl snap electrodes (https://shop.openbci.com/products/eeg-snap-electrodes) would be necessary and to my understanding, that it is rarely needed unless there is visible residue. However, I am now in the process of planning an experiment with volunteer subjects and I would like to primarily use these metal electrodes in my experiment. Usually it's a good idea to disinfect EEG caps and electrodes in between subjects, thus what would be a good procedure to disinfect these electrodes without corroding them? If there is such a standard procedure where might I find the documentation for it? I would imagine using a low concentration of disinfectant would be the way to go, but I want to make sure if I can use disinfectant and what kind/brand would be recommended.
An additional question if anyone could answer it, where might I find a good site to buy EEG caps at 3 different sizes (large, medium, small) that would be compatible with these electrodes. Something like this cap I found on amazon:

Bruce, hi.
Just dousing / spraying them with isopropyl alcohol is probably sufficient. You want to avoid 'rubbing' the AgCl electrodes, because the chloride plating is thin.
