Rinse whats that?do people really rinse?
I just scrub from top to bottom.never rinse.
are you joking?
no why?
I can get away with less than 10 litres per house.
seriously? no complaint at all?
On regular cleans this can work
concept2o work like this
yes wouldn't do it on first cleans.
I start at bottom of the glass rubbing up and down in zigzags and then top to bottom sideways .
no rinse?
practice on your own house,try different techniques and flow rates
my flow is around 45psi,across the top twice, then down to the bottom then back up, move along do it again i may repeat this action depending on the size of the window and finish with a zig zag motion
