This may be a trivial Q, but didn't see any info on it. When washing your car, does the water have to be cold, luke warm, warm, or HOT? I already know the answer, "depends on what you are trying to remove", but still I thought I would ask!

 

I dont it matters but I could be wrong. I usually use warm water from the sink to mix the washing soap because I dont wanna dip my hands into a freezing cold bucket =)

 

I would avoid both extremes, anything in between is just fine......

 

I like to use warm water when possible, never hot water though
