i never have to worry about my glass getting too cold when im washing my car because i would never wash my car in the cold. h:

when you guys are talking about hot water, im assuming its not water over 110-120degrees. thats about how hot my hands can take. i filled a bucket of hot water and soap to wash my roof one time because of all the crap from the redwood tree, and it was easier than using cold water. but its more of a hassle for me to do that.
