Rubber gloves and twist with the least amount of squeeze possible. Maybe two people.
HI SB Cleaning,
Dave Willis is quite correct - this technique works very well - especially if you twist towards each other, and if neccesary, use a little PFTE spray and allow to soak before attempting.
Our new V4 poles are stepped as well as tapered, which prevents the sections over lapping to far and then sticking. Of course, this doesn't negate the need to make sure both the male and female parts of each pole section should be cleaned (washed, and wiped, and then sprayed with PTFE spray) in order to prevent them sticking together in future.
