I was thinking about doing a window cleaning course and realised the course would need to last months
Mainly due to many different types of windows, glass, heights - inside/outside etc
I would say on average a good window cleaner takes between six month's and two years to become good enough to clean ANY window on ANY building
How much would that course cost?
And my staff get this training for FREE and I even pay the buggers a monthly wage - they don't realise how lucky they are.
