Hi folks, Ive got a cust with sliding patio doors on their top bedroom but instead of the iron railings on the outside theyve gone for a glass screen and they want it cleaned both sides. I can clean it so far from inside when the doors slid open but can not reach the whole window and it looks bad half cleaned. Iwas thinking about taking the brush head off my poles an seeing if i could shape the small tubes to bend round an rinse off the glass that way.Has anyone came across the same problem ???
