Elbow grip!

Hi there! So, I have recently built up enough strength to do a forearm grip ayesha and wanted to move on to elbow before I try split grip.  The problem is... my elbow pit is apparently in a permanent state of gross sweaty slipperiness.  😕  I have tried everything-- washing with soap and water, using mighty grip, itac2, dry hands, deoderant (haha, desperation) on my elbow pit, trying early in my workout before I'm too sweaty and gross --everything!  Will I never be capable of an elbow grip?  Does anyone else have this issue, and how do you deal with it? I have a pretty sturdy extended butterfly and am tempted to just move straight on into split grip, because I'm losing hope that I will ever pull of an elbow grip anything!
