Me too. What I usually do is leave a bucket of rinse water just outside the front door so if and when my sleeve gets a tad nasty I can clean it up.
Still, the bottle speeds things along and keeps my windows slick. I like to run my squeegee nice and wet, but I don't need to be constantly dunking the washer. And, as aforementioned, many customers appreciate me leaving the bucket outside.
Not saying mine is the only way to do it, but it works for me, my work flow, and my customers so that's really all anyone can ask.
