[frames to panes]

Yesterday we seemed to have had a sandstorm in my area, my windows were the worst i have seen them in fifteen years, the cars were covered in muck - a right old mess. Today the wind's dropped and it rained in the night and it's rained this afternoon. I've just wandered out into the conservatory totally fed up with things in general and have noticed my windows that face the weather are practically spotless apart from the rain. Must have been a good tds in the night.
