Washing your car with hot water

[Garducio]

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,
Grady.

Be careful using hot water on cold glass? The paint will be fine but it you have cold glass with a chip or hairline crack, putting hot water on it will cause more damage to the glass!

I use what I would call warm water in my buckets on occasion. Sure makes dipping your hands in there more bearable.

ok didn't really think about that. but when I say hot water it's not boiling water. Just worm enough for where I can easily put my hands in the water. But will keep that in mind.
Thanks man.

Warm water should work just fine.

If anything, I think warm water actually helps in the process of breaking down/loosening dirt and grime.

I use hot water all the time as long as the temp isn't bellow freezing then I use warm water.

Not a problem at all for the car.

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.

I recently figured out (don't know why it took me so long to think of this) that since the washing machine is right off the garage, and the hot water valve has hose threads, that I could just hook a hose to the hot water supply for the washer and stretch it out to the driveway. If your water heater is in the garage I guess you could also add a spigot to the main line there.
