Wash oranges in warm, soapy water. Rinse well.

Slice oranges in half and remove pulp either with a hand press juice or a knife. Slice peels in half and pack tightly in a quart sized glass jar.

Fill the jar with white vinegar to just above the peels. Use a fermentation weight or a clean stone to keep the peels below the surface of the liquid.

Screw on the lid and leave on the counter for two weeks.

Strain the orange-infused vinegar and dispose of the peels (do not compost).

Dilute the vinegar with water 50-50 in spray bottles for nontoxic cleaning in the kitchen and bathrooms. Works for windows at the same or slightly lower dilution ratio (1:1 or 1:2).
