How to wash in winter.

A couple quick suggestions:



Visit the local wand wash to knock off the chunks of snow & ice, keep the nozzle at least 2 - 3 feet from the paint & don't aim directly at the car, keep the spray moving at an angle. When standing by the LF tire, do the left side door, when standing by the left side door do the left read quarter & so on.



At the wand wash, choose the rinse cycle only. Don't go for the detergent (too harsh) & don't opt for the "hot wax" ..... no explanation needed.



If you can, find out if the wand wash facility uses fresh water or recycled water. If it's recycled, look for another facility.



If you keep your hose in the basement (meaning you may have to drag it through part of the house to get to the garage) simply screw the male & female ends of the hose together to eliminate dripping water in the house during the walk-through.



Buy some of the cheap $1 yellow dish washing gloves & use 'em when you're hand washing outside if the outside temp permits. Use warm (not hot) water in the wash bucket & hotter water in the rinse bucket and your hands will not suffer.

If need be, I will test the same experiment on my windshield this week. I will pour equal amounts of warm/cold water on my windshield and let it run down, and monitoring it to see when they freeze.



But that 2nd site claims that the Mpemba Effect was first noticed when the kid put his hot water in the freezer and it froze first. :confused: That seems awfully similar to my experiment.

I am very sorry for hijacking this thread.



I wonder if the cups are providing some kind of thermal insulation as this would expose the surface layer to the greatest amount of temperature variation.



Maybe someone with a greater understanding of physics could provide more assistance or maybe post on one of the physics forums
 
As I said, I completely encourage others to try the experiment too. I am not convinced either way at this point. Maybe I'll dump some water on the street or something as another test.
 
This has nothing to do with car washing but if you want to experiment with something really cool try this:



A really cold day, like less than 5*F, is required. Take a cup of boiling water, throw the water into the air, and watch it turn to steam .... vapor ... whatever.



Instant liquid to gaseous transformation.
 
In my humble opinon. If you live in an area that has lots of snow and salt. You need to take the car to an car wash and get the undercarriage wash. ( that is if you plan to keep the car a long time) A few swirls etc. is better than rust. You can polish out the swirls in the spring. Try to polish out rust- it won't work.

I do not trust the quick wash stuff if the car is really dirty - my car's owner manual say's lots of water for a car wash.
 
btw, the QEW stuff is awesome. I just washed again (third time or fourth time this winter) today.

You can see the orange peel reflecting light in all its glory. I think that layer of Zaino Z5 is really struggling now.



Still, awesome to have a clean car in the winter! w00t!
 
I think it is better to take to a car wash than let it sit with sand and salt.

Take the swirls out when the weather gets better.
