My xpole was very slippery too but I use rubbing alcohol to clean it and only when needed. To get rid of the slippery film, I literally rubbed by grip cream (tite grip) all over the pole – it made it gritty – then used the rubbing alcohol to clean it properly and it has been great since! I find that when I get dry skin, it makes it impossible to grip too but using some on my legs (I never put it on my hands but I rub my legs together to spread the spray) I stick like glue!
I know I was ready to give up with my pole before I decided to rub the grip all over it, but thats all completely changed now!
