Washing Windows in the Cold

it is freezing in Memphis. Most window washers stayed home in bed....what did we do? We were out washing. If our regular cleaning solution can't be used due to the extreme temps we innovate. Our "special" solution we use on cold days lets us wash windows even when it is down to single digits. What is this "special" solution that we use? I will give you one guess, "sesame seed bun and special sauce" .............you really didn't think I would tell you? Did you?
