I started doing this in the spring in Texas when it was already in the 90's. Now I'm in Arkansas and its in the 50's-60's. Is there a temp at which the chems (cider) don't work as well? Scott
We wash trucks down to about 27. When we do houses we like stay above 40. We washed a Lowes in 12degree weather. They signed a waiver about the ice and we did it. Most the water was evaporated anyway.
We do seem to have to kick up the roof mix as it gets colder too. May be because of the lower quality of SH as the pool season winds down. Contrary to popular belief our season in not just 9 months.
When January rolls around we have some shopping centers that need to be done. I try and choose a night where it stays above freezing but we have been out when it was around 30.
It doesnt get very cold here, but we did clean last year on the rare occasions it got down into the 30's. You just have to kick up your mix a little, and let it dwell a little longer. You may also notice that you have to spray an extra coat or 2.
