Hi guys
I've suffered with my neck and shoulder and rib cage, gradually getting to grips with it,
one main aggravation was always lifting to rinse and looking up
So I changed to fan jets, they take some getting used too, I now never lift to rinse although hot water makes it easier I admit
But you can develop your own method, and you do need a brush that doesn't hold the muck,
I love fan jets and would never go back, if leaving brush on glass you need to move dirt of glass similar to traditional method then back up for final rinse, it's a real art in the sense the brush stays on the glass at all times and I think water usage seems less not sure I use about 350 a day, it's less strain on the body overall
