  • White vinegar

  • Water

Although electric steam sterilizers that kill bacteria and germs on baby bottles are sterile cleaning devices, these units do require regular cleaning. You must thoroughly dry your unit after every use to remove moisture that promotes the growth of bacteria, mold, and other microorganisms. In addition, you must regularly descale your unit to remove mineral deposits and chemicals that build up on the hot plate and can cause it to work less efficiently.


Step 1

Turn off and unplug your electric steam sterilizer; allow it to cool at least an hour before cleaning.

Step 2

Disassemble the unit and pour out any excess water from the hot plate/base.

Step 3

Wipe the unit's trays, basket (if applicable), and base with a dry, non-textured, lint-free microfiber cloth after every use.

Step 4

Descale the hot plate and base with a solution of vinegar and water every two weeks. Mix 1 part vinegar with 4 parts water and pour the solution into the hot plate up to the fill line. Wait at least a half hour or until all of the scale has dissolved. Pour out the descaling solution, pour water into the plate to rinse, then pour out the water. When finished, wipe the hot plate and base with your cloth to dry.

Step 5

Reassemble the unit.


Never use abrasives, antibacterial cleaners, bleach, or other harsh chemical cleaners or commercial descalers to clean any part of your unit.

Never immerse the hot plate and base of your unit in water, because you can permanently damage the unit, making it unusable. For the same reason, never overfill it with water or cleaning solution.
