I’m the designated bike washer in our house, usually four one after another, along with the ironing but not at the same time.
Prior to having our garage broken into last year and two bikes stolen I used to wash them on the pavement infront of the house and let all the filth go into the drain further down the road, I even had a bracket that clipped onto the fence to jam the wheel into.
Since then I have become paranoid on who may see them so have reverted to stealth washing round the back of the house either on the grass or on the patio.
After reading all this Im going to adapt my bracket so that I can now wash them at the top of the garden and utilise the pebbled bit that Kevin has never got round to landscaping since we moved the shed 10 years ago.
