All you need is a drop of the apple and mint solution for a smear-clear result. 
We recommend dropping the solution on to clean, machine-washable cloth, and then using a second microfibre cloth to eliminate any last streaks. 
Buy your mirror cleaner as an individual sachet, or as part of a five-piece box.
Add your sachet to your own reusable bottle and simply drop, fill with 500ml of warm water, shake, repeat. One bottle; zero waste
