Keep a rag/sill cloth on you & wipe the pole hose after every job (especialy if the ground &/or hose is wet), this is the main cause of pole wear as the hose takes dirt up inside the pole which gets between the sections & causes abrasion each time you extend/retract the pole. Take the pole sections apart every week (or when required) & wash the inside of every section with a hose pipe, then wipe the outside of each section with a cloth & then put them back together. This should give you the longest life expectancy of your new pole.
