I have a good percentage of my work tht only really neds the off window claning. But as the agreement is mothly etc i just turn up and clean everything. I see it the same as rwc. My of my custmers would be well chuffed if they had a monthly clen and they looked goodf for most of that month.
I have said to some older customers that it is like takin candy from a baby, and am happy to go 8 w0eekly instead if they prefer.
