Thanks all. How long would one pad last before it needs changing to be washed? I know it depends on how dirty a window is.
If you have been maintaining the windows and just doing a quick once over to remove light dust/fingermarks, you can clean a reasonable number of windows with a pad (I err on the side of caution and change them quite frequently). However, if it's a first clean, have a good stash of pads and maybe re-do the job after washing and drying them. They really are best used on maintenance work but sometimes it's not practical.
The main issue I've experienced on maintenance work is on plastic partitions. The more plastic it is, the more prone to smears (it doesn't work so well on more flexible, perspex-like sheets). However, some partitions come up just fine so I'm thinking it might be determined by how the sheets are made and the materials used. There was one job (mostly perspex) where I had to squeegee everything - sometimes from a pole. I used dry pads to tidy up around the edges. Even then it was less than perfect but they were OK about it because it was a disco where the lighting was very low anyway. Also, I pre-warned them of possible quality issues and said that if they wanted work at height, the cost would be very high as it would be on a tower or lift. They went for the cheaper option (quite relieved about that as I don't have a tower or lift
).
