I have a school i clean every year or that. There are screens in it at 2nd storey level that can only be cleaned from a flight of stairs below . Problem is there is not much room for operating normal techniques and no way of putting a ladder on most of it. Now i soldier on at it every year and produce an acceptable level of quality but dread doing it . Is there anything im missing here lads like is there internal high level techniques or tools that make things like this much easier. I just put the attachment on my slx so I can use sponge and squeegee as per . Thanks in advance
