WELL I BROKE ANOTHER WINDOW on mon , just cleaned the windows at 25 degs water temp
stepped back started cleaning the next one and half way through that one it went CRACK from
top to bottom oh dear I said lol and that was a few minutes after cleaning it
20 degs max I think in this weather
V8Edd,
couple of questions for you (regarding breaking yet another window).....
how cold was it outside?
was it early morning?
did you spend a long time cleaning the window that broke?
did you have a high flow rate of water?
was you working in the shade?
was their a steamy haze coming off the glass whilst you was cleaning it?
was it a double glazed unit?
I'm curious and interested because I have 3 customers all with double glazed units, 2 had their units shatter to pieces and one crack right along the glass but at a later date when I wasn't even around. What concerns me is wether the hot water is putting stresses on the glass and kind of 'tempering' the glass making it weaker similar to heating metals and allowing them to cool too quickly making them stronger but more brittle.
I'd appreciate your honest opinions as using hot water even after 2years is still a learning curve for me.
