Disinfectant: Sinks, draining boards, chopping boards, worktops. Chemical free, fresh and natural. Try washing over any surface that you want to clear of bacteria with your trusty lemon juice.
Glass cleaning: Just like vinegar, glass loves lemon juice. If you rub a lemon wedge over your mirror, followed with a damp cloth, you will be able to buff to a perfect shine. Cheap and effective!
Dishwasher freshener: Cut your lemon into chunks and press over a couple of rungs of the dishwasher. When you run the dishwasher, the lemon will degrease the appliance, whilst leaving a fresh lemon scent.
Fridge freshener: Leave a cut lemon in your fridge to rid it of those smells that build up. Lasts for some time. Just replace when ready.
