This is one of the Challenges that I use to think of other things to add on the Challenge list - amazing what you can think of when 'cleaning the windows' is the alternative.
However, if life is like a box of chocolates, you can't always avoid that hard toffee one that breaks your teeth, so this morning I manned up, put on the waterproof apron and marigolds, and got the steps, bucket, sponge, cloth and squeegy out.
It took bloody ages to do both inside and out - I certainly had ample time to contemplate the astonishing number of windows there appear to be in but a modest end terrace (that's 10, including two Velux, plus a couple of glass doors, and the window over the top of the front door).
The weather was kind, though, the rain holding off until just after I'd finished, and the real bonus is that this time, I managed not to tip the bucket of water off the top of the steps all down my front, whilst in the front garden...
A Challenge well and truly done!
