If a rinse bar goes above the brush with the flow I like to use it’ll always hit the top frame on the final rinse down,I like to clean the top frame and then rinse from the top of the glass.
An above rinse on anything apart from plastic I can see problems coming some timber windows I avoid the top frame section on a regular clean,a central flow of water is far more reliable and accurate let’s not try to over engineer things,central jets are perfect let’s just have 2 more to go with em that would be an improvement.
