Hi Mark,
Well it's anything but 32 here !!!!!!!!
Seriously, you may find your usage of water will be high due to the rinsing required.
If and when we ever have a so called hot day it is advisable to pre rinse the window to scool down and after the clean a thorough rinse again, this helps eliminating spotting.
Regarding a distributor sending to you, well I can't see that being a problem, just a shipping cost.
As for learning how to use the system, well you will need the help of an established WFP cleaner to show you the ropes and set up your systems, it just so happens I know someone who is able to fly to Cypres for a week in the sun in return for showing you how to set up and clean. So, if you're interested, let me know and I will pack a bag lol
best wishes,
Trev
