Last week in all the snow and very board at home I desided to heat 30% of my back pack water to boiling to see what results I would get. I was amazed how much better it cleaned glass.The back pack was only luke warm it washer beter and gave the best results I have ever had on my House .It even streamed on the glass and dried faster.It has made me think there is a place for hot water. Has anyone tried this and what results have you found.
