Wash water; better warm or cold?

With ONR, is it better to have your washing water cold (like right from the hose) or warm? I think warmer will cause dirt to loosen faster/better from the wash media?
 
Whatever temp it is out of the hose? Well, unless its winter. Then I get a bucket of warm water from inside or the rinse and soap buckets.
 
I've done test in the past and found you get more suds with warm/hot water. I usually fill my bucket with hot water from the sink.
 
EDIT: Oops just noticed the original post was asking about ONR...ignore this ;).



Does the same warm water recomendation hold if using ONR?
 
I never seen a difference. I use ONR mainly so suds don't mean anything to me.



I don't think the heat from water that's cool enough to stick your hand in will make that much of a difference in terms of breaking down grime

But it does take longer to freeze when you wash you car in the winter in the northern states.
 
Thats a different case than, and would mean your using warm water for a different reason other than the OPs stated purposes.



Obviously if you live somewhere where its freezing, warmer water will be better moreso for the user.



Im just saying in general though, I doubt any water thats cool enough to not cause any scalds or burns isnt really going to be doing any more dissolving/loosening of dirt than regular tap water.
 
One thing I have noticed with warm/hot water, at least here in the Northeast where I have well water. There are more dissolved minerals and the like in hot water and this can leave more waterspots than cold.



Not that you can't get waterspots to go away, I just find it annoying.
