Cleaning the glasshouse
Does anybody have an ORGANIC CLEANING option for the roof panes of the my glasshouse? The pine trees from our neighbour have grown a lot and dumped their dead needles on our glasshouse roof. I didn't mind for a long time while we had intense sunshine. But I tolerated them for too long. Now I wanted to clean the roof to get more light inside.
I discovered that we have an intense red film on the glass that is only removable with a lot of elbow grease. Even the water blaster that I reluctantly tried didn't work.
