The Great Water Debate

:confused: Just wanted a few opinions on the Great Water Debate. The 2 guys I work with fight over which should be used (Hot water or Cold water). They have some interesting theories and what not but I just figured maybe you guys could give me some input on which you like better. One guy swears that hot water cleans better and doesnt leave water spots on the car and the other guys says the only difference is size or speed of the moving molecules (dont ask i dont know). Any way figured I would ask the pro`s. I use hot water at work and at home I only have cold in the garage. I dont really notice any difference. What do you guys think?:confused:

Hope I can help-
First off, hot water would evaporate faster and would thus cause more water spots. Also, hotter water can hold higher concentrations of dissolved ions (salt) and this may even enhance water spotting!

Hot water has the advantage of being able to help dissolve and clean stubborn dirt (especially greasy stuff), however a good soap/shampoo will do this just the same!

I hope this answers your questions satisfactorily. If you need more info, let me know.

Hey THANKS!
Makes perfect sense to me.
Like I said those 2 guys were going at it a couple times of the stupid water temp.
I say clean the car and shut up.

Depending on the temp of the hot water, wouldn`t that aid the deterioration of the wax and cause a dull appearance? :(

The water would have to be above boiling temp for that to matter.

I heard that some waxes will begin to "liquify" at lower temps? Was I lied to? Or is that something you only need to worry about when applying? "No direct sunlight,....vehicle cool to the touch"

"Lied to" may be too strong. There are several vendors offering products which can be applied in the direct sun. Check out Poorboy`s products as an example.

I supose if it`s a cheap enough wax that contains a high amount of wax that isn`t carnuba like beeswax and parafin then it might possibly when using super hot water. But any good wax will not do this.

If the wax contained oils (which many do to enhance that warm glow) at too high a concentration, the wax would melt at a lower temperature.
