Moss in greenhouse

I have moss growing on the inside of the greenhouse between the panes and the frame. It pushes the panes out letting water leak in. I normally have to tease it out with my nails. Any ideas as to a better way or a preventative measure?

I use a plastic plant label to remove it from my greenhouse. An old toothbrush is useful as well.
I was out attacking it with a kitchen knife today and I have all the visible bits dug out. It is only on the downside of the sloping panes so I was thinking of mixing up some bleach in a spray bottle and spraying along the frames on a dry day. Do you think the bleach will kill the moss or should I try a weak solution of Jeyes fluid?
It may not be necessary to use either. I use my hose on a strong jet which usually dislodges anything between the panes. Then the bits which haven't been dislodged on the first attempt use a plant label to losen more and repeat the process.
