Care Instructions

Washing & Sterilizing Glass Bottles

Everyday Cleaning
  • Hand washing is recommended for best clarity

  • Mild liquid hand soap works especially well for a crystal-clear finish

  • Use a soft bottle brush if needed

  • Rinse thoroughly and air dry upside down

Before First Use
  • Wash bottles thoroughly with warm water and mild soap

  • Rinse well to remove any residue

  • Allow bottles to air dry completely

Dishwasher Use
  • Dishwasher safe (top rack recommended)

  • Avoid overcrowding to prevent contact with other items

  • Remove the swing top mechanism to prevent it from getting caught up in the spray arms

  • Allow bottles to cool naturally after the cycle

Sterilizing (Boiling Method – Safest Approach)
  1. Place a folded towel at the bottom of a pot

  2. Insert bottles while the water is still cool (remove gaskets first)

  3. Fill with tap water until bottles are fully submerged

  4. Heat on medium until the water reaches a gentle boil

  5. Once boiling starts, turn off the heat

  6. Let bottles remain in the hot water to cool down gradually

  7. Remove carefully and air dry

✅ This gradual heating and cooling method greatly reduces the risk of thermal shock.

  • Avoid sudden temperature changes

  • Never place cold bottles directly into boiling water

  • Do not pour boiling water into a cold bottle

  • Glass is breakable if dropped or mishandled

Storage Tips
Important Safety Notes
  • Remove gaskets before boiling or dishwasher cycles

  • Wash gaskets separately with warm water and mild soap

  • Ensure gaskets are fully dry before reassembly

Silicone Gasket Care
  • Store bottles completely dry

  • Keep lids open if storing long-term

  • Avoid stacking without padding
