Cleaning

Why is it when you have spent hours cleaning the car or the windows, it either rains heavily or a bird passes by and decides to excrete all over your lovely clean surfaces!

Someone is having a laugh!  Not only that, but I've also had to contend with the blossom from the trees blowing down my street and congregating on said clean windows and car. Does Mother Nature think I have an extra 2.5 hours to spare all over again tomorrow?!

Can anyone recommend a cleaner, or tarpaulin big enough to cover the house!

Rant over.
