Cold weather rinseless washing
What's the coldest temperature you've successfully rinseless washed your car (or a customers) using hot/warm water while outdoors? How cold is too cold?
I've successfully gone down to 30-35 before, but curious if those limits can be pushed at all. I'm using Meguiars D114 if that makes much of a difference.

Re: Cold weather rinseless washing
Last year when we had that "Polar Vortex" it didn't go above freezing for almost 3 weeks. I decided I really need to wash my car. The temperature was 20 degrees. I used hot water, washed one panel, then dried it before it could freeze. If I didn't move quickly the water would have easily froze. I had to divide the hood up into two sections to be on the safe side. I wouldn't want to do a rinseless at that temperature again, too much risk at freezing and scratching the paint. During winter I would feel comfortable doing a rinseless at 32.1 degrees or higher.

Re: Cold weather rinseless washing
•D114 may help to lower the D114/Water (RW)
solution's freeze-point somewhat below 32°F.
-How much below, though?
•As to using hot water to wash vehicles in
freezing/near freezing temps:
-Hot water has been known to freeze faster
than cold water.
•Question:
-If D114 does help lower the freeze-point of water...
would the use of hot water, for the RW-solution, be
more, or less, beneficial in achieving that goal?

I've wondered if rinseless washes might lower the freeze point.
Any idea of what it would be in rinseless washes that might do this?

Re: Cold weather rinseless washing
Hot water freeze faster..... how?
If im at 70° and need to get to 32° thats 38° to lower to freezing point. i would have a higher margin than if i started at say 50° giving me 18° to get to freezing!

Re: Cold weather rinseless washing
Outdoors D114 RW, 30-32* is my limit.
In a garage D114 RW, 25-28*.
Just Power Wash and a quick lite dry, I did 18* last winter at 9AM with the sun shining.

True, the hot water lines in my RV will freeze before the cold water lines. I think I read somewhere that molecules get changed some how during the heating cycle.

Huh that's crazy! You'd think that wouldn't be the case. Now im going to have to look that up, so i can add the answer to my wealth of useless knowledge! Lol

Water has both:
-covalent bonding...where the atoms (between the
two hydrogen and the one oxygen) share an electron;
-and: hydrogen bonding...formed between
different water molecules (where the positive
hydrogens of one water molecule become attracted
to the negative oxygens of another water molecule).
IMO:
It's those daggone hydrogen bonds that account
for a lot of water’s strange properties; such as:
-Water becomes less dense when frozen...aka:
"The ice floats phenomenon".
