Some of these posts dont seem to make sense :
You have a lot saying that it does not take 3 cleans and can been done in one , Then they say that you might have to go over the window again because of spots or needs another clean
I am one of the window cleaners that would say 3 cleans to my customers and I will tell you why,
Most times the windows come good on a first clean and when I say first clean I like to go over the window twice ( if you count that as a first clean
)
By saying it will come good on a third clean gives me scope if there is a problem window
If you do not say 3 cleans and one of the windows spots then you have to explain to the customer that it will come clean next time and thats if they give you that chance ... If you say 3 cleans then you have covered your back if the window is a problem window
Now I know that there are people that say that they will not leave the house untill it has come clean :
But thats OK if you have the time
You can clean the windows wait for them to dry then see if one or two that have spotted then clean them again and you need to wait again to see if they dry good this time :
OR
you can say that it might take 2 or 3 cleans
