Washing your car with hot water

[AeroCleanse]

Yes, hot water can help as others mentioned. Most water heaters are set around 140F, and by the time it gets atomized out your hose nozzle and reaches the paint it probably drops quite a bit.

Or if you use a rinseless wash.

This winter was the first time I've ever done a rinseless wash and warm water helps a ton.

Be careful hooking directly up to a hot water tank, that water is hot and you need a hose rated for high heat. If that things bursts you could have some issues....

I use hot water all the time in winter and have not had any problems. Like mentioned it sure does feel good to put your hands in warm water when it's cold outside.

Yea today I detailed the interior of my car and man my finger were frozen. I couldn't feel them at all. and when I washed my car I had to have worm to hot water. I can say I was happy to wash my car. wormed up my hands real well lol But yea I'm not using hot boiling water just worm enough not to freeze my hands.

Being from WNY I've done warm water washes for years when the temp is at or slightly above freezing, warm water in the soapy water bucket and cold water to rinse from a hose or from another bucket. It'll be easier this year with DG rinseless after a trip to the touchless wand wash to get rid of the majority of the salt, grime, and chunks.

I keep the cold hands problem manageable by wearing those yellow gloves sold in the dish soap section, pretty durable & your hands almost never get wet but you still have all the dexterity you need.

My hands might get cold but they never get wet, stinging, what-the-hell-was-I-thinking cold.

Quick question guys. Seems it's pretty cold out there, when I wash my car I fill the buckets up with hot water. Now I don't think it should be bad for the car or anything having hot water on it for a few seconds but just wanted to make sure . Do you all do that also or no??
Thanks,

Are you concerned about the vehicle's clear-coat paint having to experience some unwanted: Thermal stressing?

That phenomenon can actually damage clear-coat paint...over time, and if it occurs often enough.

Your above outlined car-washing process seems far from going to those extremes.

I have a tankless water heater and an outdoor faucet that supplies hot water. Ours is set to 120. They told us no matter what you have it set to it is only designed to raise temp of water 50 degrees above ground water temp. I am thoroughly impressed with it thus far. No issues with using hot water. Even though it may be 40 degrees the sun hitting the car panels warms it. So it isn't that shocking to it. I won't wash under 40, the suds freeze.
