Begin by cleaning and sterilizing the spray bottle. Wash it thoroughly with hot, soapy water, and rinse well. Disinfect the bottle with a high-percentage isopropyl alcohol (70% or higher). Apply the alcohol to a clean cloth or cotton ball and wipe the bottle thoroughly, including the cap and spray nozzle. Allow it to air dry completely before using. You could also submerge the bottle in a pot of boiling water for about 10 minutes. Let cool and dry completely.

In a small bowl or measuring cup, combine the distilled water and vodka/witch hazel. Stir well to mix.

Add the lavender essential oil and chamomile essential oil (if using) to the water and vodka/witch hazel mixture. Stir again to combine all the ingredients thoroughly.

Carefully pour the mixture into the sterilized spray bottle, using a funnel if needed.

Screw on the spray bottle cap tightly to avoid leakage.

Shake the bottle gently to blend the oils with the water and vodka/witch hazel mixture.

Your lavender linen spray is now ready to use!
