Cleaning greenhouses

Please would someone advise me on what products to use to clean a polycarbonate greenhouse. I can't use Jeyes Fluid because it's not sold in France. Is washing up liquid enough? Can you make the polycarbonate go brittle if you use the wrong solution?

    How do you clear the mossy stuff which gets stuck between the panes of glass on a GH?
