Bicarbonate All-Purpose Cleaning Spray

Method

1. Pour the warm water into the spray bottle first. Doing this before the bicarbonate stops it clumping at the bottom of the bottle.
2. Add the bicarbonate of soda and swirl gently until most of it dissolves. A little sediment is fine — it'll suspend evenly when you shake the bottle later.
3. Add the vinegar slowly. The mixture will fizz for about ten seconds — this is just the bicarbonate and acid neutralising slightly. Wait until it settles before sealing the bottle.
4. Finish with the essential oil. Lemon for kitchens (cuts grease), tea tree for bathrooms (mild antibacterial). Screw the cap on and shake to combine.
5. Use. Spray onto surfaces and wipe with a microfibre cloth. Shake the bottle before each use because the bicarbonate settles between cleans.
