biggest majority of mine is 4 weekly, but I let my customers decide. I have weekly cleans, but thats shops, and do some residentials 8 weekly and even 12 weekly.
Customers always ask me how often do I think they should be done, and I ask...
"That depends...",
"...Do you want them maintained clean, or just cleaned when they are dirty"
And they always say maintained, so I suggest trying 4 weekly and changing it if they want once they see the biuld up on the glass, but most just stick to 4 weekly.
I am suprised to here people saying they have alot of 2 weekly jobs. Is that shops or residential.
