I would like to know if hot water is better at washing "EXTERIOR" and cleaning than cold water. "PLEASE" I know it sounds like a dumb question but whats your thoughts on this?

Also,do you think it takes off wax? we all know COLD WATER hardens wax and is good to use in the cure process.Is the hot soap filled bucket also a potential problem. :inspector::wow::idea
 
I like a warm bucket of water. Even if you were to use "HOT" water it wouldn't be to the temperature that would melt wax. Use which ever your hands feel best in.
 
In winter when the temps are very low, I'd be afraid to use "hot"
water. My reasoning is that the damage the rapid temp change could cause to the paint.
 
I agree with Ron. It's nothing I would do on a personal car, but I suppose hot water wouldn't have any really bad effects in the cold months. If the paint is already really cold, the hot water wont make it any hotter than it would get on a summer day. But its all personal preference I guess, I just wouldn't do it on my own partly because its more of a hassle
 
In the winter I use warm water just enough to make it feel comfortable.
That would not be enough to remove wax.
As far as paint damage I have a heated garage so 110 degree water on 70 degree paint will do no harm either. :)

My fear is not the temp, but the speed/rate of how fast it goes from one to the other.

Warm water would be no different than using a hose to rinse on a hot day you are spraying 50 degree water on a surface twice that temp.

If you don't know the answer, it isn't a dumb question. How else do we learn?

Try rinsing a dirty dish under cold running water, then try it with hot/warm water. I think you will answer your own question after you see the difference.

As far as removing wax/sealant, I don't seem to see a problem when I use hot/warm water for rinseless washing. I tend to apply more LSP every 4 to 6 weeks so I'm not really a good test of durability.

FWIW, I have been using hot water for rinseless washes for 2+ years now and have had nothing but good results with that process. I fill my jugs with hot water and my rinseless wash in the basement, carry it to the garage and pour it in my wash bucket. It has usually cooled enough that I can put my hands in it with no problem.
My hot water heater is not set to heat the water hot enough to burn you. While it might be uncomfortable straight from the faucet, you can safely hold your hand under it with no injury. We started doing that many years ago to prevent the kids from burning themselves with scalding hot water. 140 degree water burns skin in seconds, 120 degree water in 10 minutes.
