ionics say their thermo customers in germany work up to -10 !
was strange did a row of houses all the same -2, did the gutters and facias on one fine, but froze on a cons roof only?
one house we did -3 it was an initial clean and it just froze and sealed the dirt into the window / frame.
but then i went to do some offices the other day -4 wfp came up lovely did sometrad with screenwash , not sure if i got dilution ratios wrong but it leaves streaks everywere not worth it in my view
would be interesting to hear what the biggest firms do with loads of vans- wonder if they use hot systems or iso or what..
remember guys dont eat the yellow snow
