I have usually tried to use warm water opposed to cold. It just seems that it cleans the grime off easier. My question is... is warm water bad for the waxes and polishes that have been applied? Does it take off the coats of wax faster than regular temp hose water?

Any info on this matter would be greatly appreciated.....

Warm water won't hurt the LSP. I wash with whatever comes out of the hose.

Rate of reaction and solubility (among many other things) increase as temp increases, which is why "grime is cut easier" on both your car and your dishes with hot water. Temperature also tends to make things softer, like wax and grease. But you would need to be actively heating up the water (or cooling it) to notice when washing your car. Generally, whatever comes out of the hose is fine.

From the waxing pros, I heard you should always use cold water because it protects the clear coat and the paint. I used to use piping hot water because it made sense it would remove more dirt, but it really depends on the quality of the cleaning products used. I've switched to cold water + good cleaning products and I still get the same shine.

got good info above...
i would only add that you dont want to "shock the paint"-
if its warm, dont use cold water (which is one reason we wash cars that have cooled down in the shade), and if its cold, dont use hot water.

as above, whatever comes outta the hose is pretty much a good temp

there are some scientific reasons to use warmer temps if you are trying to do volume (like in a carwash)... kinda gasolina's point i think-

let me see if i can track down something, but the main thing you need to know is that for us, the hose temp is good (prob should add that if the hose has been sitting in the hot sun, bleed it out before washing)...

here you go- this is "fantasy reading"- good to learn theory, but it wont apply to us. it applies to the big car wash places (they dont care about long-term effects or swirls, or any of the stuff that we focus on- they are more into how to get the most number of cars clean for the least amount of money):
