Vinegar has long been known as an excellent homemade window cleaner. However, its somewhat sour, pungent smell may discourage some people from using it. Here's a little suggestion for a synergy that should make for a more pleasant olfactory experience.

• Two thirds water
• One third white or cider vinegar
• 20 to 50 drops of essential oils 

Aromatic synergy suggestion

• 10 drops geranium essential oil
• 5 drops lemon essential oil
• 5 drops bergamot essential oil

Combine all ingredients in a 1-litre spray bottle.
