We got our Rapido V56 in January and of course haven't had much practise with it apart from over wintering. We have discovered that the insect blinds/nets have a bit of mildew on them. I have tried cleaning them with a mild detergent solution and a gentle cloth and some comes out but there is still a bit left as well as where the blind meets the fixture. Does anyone have a good solution as to the best way to clean them ? and how do I keep mildew free ?? Thanks ....
