Fill a jar with vinegar ⅔ of the way full.
Throw your citrus peels into the jar as you go. Allow to infuse for at least a week.
Strain the vinegar and discard the peels - I pop ours in the compost bin.
To make all-purpose cleaner, fill your spray bottle with 50% vinegar and 50% Water.
To use: Spray onto a surface and wipe clean with a damp cloth.
Initially, this will smell of vinegar, however, the vinegar scent quickly dissipates and you are left with a fresh citrus scent.
Do NOT use this cleaner on natural stone countertops or tiles. Extended use of vinegar can cause pitting in natural stone.
