Cleaning the dome
After more than 3 years in place, the pristine white dome was no more. Especially on the Southern side, it had turned a grungy green, although from a distance, the overall impression was still white.
Today I sponged on some sodium hypochlorite in the form of "30 second Outdoor Cleaner" that I got from the local hardware. A rinse with the hose then revealed the pristine white again.
Because my dome is over 5 metres tall, I can't quite reach all of it from the ladder or from the slot, so the plan is to put a sponge on a stick to complete the job. Anyway, the photo shows you how well it is working!
