@Alfred Opiyo , @Ann , Any insights?I have a green house but its dirty on top, its black sunlight cannot go through it easily, how do i clean it without damaging? Is there a specific chemical i can use?
If its dust, then it can be washed using a house pipe under high pressure.Probably dust which accumulates
Dust or shooting substances? Try chlorinated detergent e.g chlorine or just powder soap Omo and the likes applied under high pressure if you can get motorized spray pump you're good to go. An ordinary spraying pump can also do but may not give excellent result as the formerIts a black coating on the outside which does not allow light to penetrate well
