If you clean windows the same way with cold as you do hot or at the same speed that’s when you can see the difference,that’s why with hot it’s quicker it breaks everything down on the glass quicker. If you scrub a really dirty window with cold water it shifts the top layer but you have to keep scrubbing to disturb it all on the glass,the hot water alone with no scrubbing will move some of the dirt I’ve tried this and a job with balcony railings I can clean to a good standard by just holding hot water over the glass with no agitation.
This is why less passes are needed over a window with hot water the heat from the water breaks up the dirt on its own and little scrubbing is needed,with cold water the only thing breaking down the dirt is the brush the cold water will just run over the top of the dirt.
As hard as that was to read, I get all that but that’s not what I asked.
I’ll try one more time, see if you can comprehend the question...
You said cold water spots windows but hot water doesn’t. Nothing about agitation or time, just that cold water spots and hot doesn’t.
So...assuming that’s true, why?
I dont care about how long you take with cold, whether you may get whiplash with hotwater or how greasy your dinner plate is.
I just want to know why cold spots and hot doesn’t.
(It’s ok to say I don’t know by the way, I wont think any less of you than I already do)
