Following on from our conversation yesterday about vents I was thinking about this today at work and figured I'd give it a go, cleaning vents above the glass in the usual manner. I have to admit I think I failed pretty miserably. The vents looked clean which is ace but I couldn't be sure how the glass would look after I'd left. The top bar between vent and glass had some nasty drops of dirty looking water accumulating on it.
Anyway, could you therefore make a video of how you go about cleaning vents without leaving the glass grubby as hell and maybe include some commentary such as 'Water On' at this point or 'Off' so I can see how it's done.
Cheers. Matt.
