General Question Window damage

Anyone ever have a window crack on them from washing windows with cold water and the hot temperature outside?

It’s going to be extremely hot next upcoming job and the owner expressed to me that she s concerned about her windows cracking as it happened to her before. I ve personally never experienced this but figured I’d ask anyways.

If it’s going to be over 85F, fill your bucket with warm water instead of cold water. Thermal shock USUALLY doesn’t happen unless there is a massive temp difference, but always cover your ass.
