I also have a stainless pole and, lately, have found it excessively slippery. This normally isn't a problem, but our dew point is significantly higher lately than normal. I'm wondering if that's part of it. What works for me even when it is this slippery is to rub a tiny bit of iTac into the palm of my hand and rub them together to soften and spread it out. Dry Hands hasn't done it lately, but I got this on recommendation from my instructor who uses it religiously haha!

My instructor has recently started teaching beginning pole on Tuesdays. She's amazing. She does Zoom classes all week. Until Shine Fitness in Las Vegas re-opened, I was taking 6+ classes a week with her and have noticeably improved: Jenyne Butterfly Zoom Classes
