I've had my greenhouse for 35 years. It's a standard 10ft x 8ft one on a concrete base into which it was bolted when the concrete was still soft. As I get older, the annual cleaning of the glazing gets more and more of a problem.
The basic probem arises from the fact that there are many fully grown beech, sycamore and other trees just to the north and northwest of it. This creates ideal conditions for intense soiling inside and out of the glazing. Inside is the growth of what I assume to be some harmless type of mould and externally, all the usual tree secretions. In short, unless I clean the glass every year, it might as well be a canvas tent
As I get older (78 in a couple of months), I feel disinclined to use step-ladders around glass and have taken to using the pressure washer. This is fine for the exterior, but I end up totally soaked when washing inside.
Does anyone have any tips for painlessly washing the interior glass surfaces of a greenhouse?
