I cleaned a 4 storey building with my wfp system today and I'm worried sick now!
The windows on the building have not been cleaned for over a year and most of the glass was covered In welded on bird s**t.
I could get some of It off but there Is still a lot of s**t left on the glass.
I was finding that on the 3rd & fourth floor I couldn't get the required pressure that I needed to really scrub It off!
The glass came up really sparkling appart from the odd bird mess still left on there
It's now time to send In the bill
Should I knock some money off my price? Any Ideas?
P.S. They only want It cleaned maybe twice a year
