I originally bought this as an oven rack soaking tray, but then I wanted to wash some pillows. Pillows washed in a washing machine lose their shape so I decided to soak one at a time in biological washing powder in my big blue tray which was exactly the right shape. Every year when the summer sun shone, I washed my pillows using the tray with no ruined pillows and no loss of shape. When you go on holiday what do you put your plant pots in? The big blue tray could take several pots and enough water to last them a week or two. After a good dozen years of use it has a crack in it - farewell!
