Pigeon poo and Balls

It's nice having a variety of birds in the garden but the pigeons roost around all over the place, including on the guttering. Hence all of the pigeon poo that gathers on the conservatory roof. Luckily, it's a small roof, only 1.5m out from the house so every so often I get a watering can and a soft brush and clean it off. We also have a window cleaner who comes every 6 weeks or so and he does the roof too, plus windowsills etc. with the long reach method.
Eric had a soft ball pit on his 1st birthday and really enjoyed it so Marlane searched out a small pit and two lots of balls for him.
All of the balls looked clean but every one of them was individually washed in hot soapy water, dried and put into bags for Johanna to take home one day. It's a lot of balls!
