i say to all my custys i clean every 4/5 weeks.
90% have them cleaned on this frequency and 10% every 8/9 weeks.
if they dont like it GET ANOTHER WINDOW CLEANER!
its your business and YOU HAVE TO RUN IT!DONT LET THE CUSTY DICTATE!
any custys who are due(2 monthly) and im not down that road to clean the monthlies that week dont get done until i am!
4/5 weeklies come first/8/9 weeklies get fitted around my monthly work unless their single stand alone accounts.if they are i usually clean these bang on time!
