"Hoppers"??
Guessing you mean top opening windows.
I use an empty spray bottle, ie like a mr muscle spray bottle in my pouch. Dilute blue unger pills in 2ltr bottles and keep topping my spray bottle. A quick light spray (enough to clean the window without drowning it taking ages to buff up or soak the scrim but enough to do the job, if that makes sense) and buff them up with scrim. These ones anyway as they had a leaded pattern on. Without led on, i mostly use a 14inch squeegee. In that case i would clean all top windows and double back cleaning windows below.
I use hard rubber in channels and cut an angle at the edges. So it doesnt ride up on the edges and so it leaves me very little detailing to do
