Andy, if they are ground floor windows blade them, then go over them with a microfibre cloth..... they will come up a treat....
If they are upstairs, you will find that not many complain about upstairs windows.... they are rarely looked out of.....
Do the top ones twice WFP if I was you, that may help, usually does with leaded
