Lemon juice is excellent for eliminating stains and odours from chopping boards; its antibacterial powers kill the build-up of germs and microorganisms, while its bleaching agent naturally lifts stains, leaving the board not only clean but sanitised. Cut a lemon in half and juice; rub the chopping board all over with the cut sides of the juiced lemon. Follow by washing the board with the juice of the lemon and a clean microfibre cloth. Let the solution sit until the stains and odours begin to fade. For tough stains, the lemon may be left on overnight, then rinsed off the following morning with warm water.
