Not sure if your greenhouse is glass or polycarbonate but a good way of
cleaning glass is with newspaper dipped in water with a bit of vinegar added
followed up by newspaper to wipe dry. Print doesn't come off. If it's glass
then you can get the algae out of the cracks using an old credit card. I
also use a hand held hoover to keep on top of smaller stuff.

Any advice on cleaning the inside of a greenhouse - top, sides and all?
