We've begun to notice that after our recordings there seems to be much residual Signa gel remaining in the electrode pedestals after a good aggitated cleaning with warm water and Hibiclens (a surgical scrub). I had assumed the gel would be water soluble and clean readily with water and detergent, but we are now finding that we must individually clean each pedestal with a cotton swab in order to get out all the remaining gel.
Does anyone have any suggestions in terms of cleaning or perhaps a different gel?
Best regards,
