Sterilisation by Chemicals Guide

Here is Lil'Kooee's guide to sterilise our products using chemical sterilisation:

Step 1: Prepare Equipment and Space

  • Wash your hands thoroughly with soap and warm water.
  • Choose a clean container or sterilising tub large enough to fully submerge all bottles and accessories.
  • Ensure the surface you place the container on is clean.

Step 2: Gather All Cleaned, Disassembled Bottle Parts

  • Ensure you have completed an initial post-feed clean for all separated bottle parts.
  • Please refer to our 'Initial Post-Feed Clean' Guide for further instructions

Step 4: Prepare the Chemical Solution

  • Use a baby-safe sterilising solution or tablet (such as sodium hypochlorite-based or other approved solutions).
  • Follow the manufacturer’s instructions for correct dosage and dilution.
  • Fill the container with enough water to fully submerge all parts.

Step 5: Submerge Equipment

  • Place all bottles and accessories fully in the solution.
  • Ensure no air bubbles are trapped inside bottles or teats.
  • Leave the items submerged for the recommended time (usually 30 minutes to 24 hours depending on the product).

Step 6: Remove and Rinse (If Required)

  • Some chemical sterilising products require rinsing with cooled, boiled, or safe tap water after sterilisation—check the manufacturer’s instructions.
  • Use clean tongs or hands washed immediately before handling the sterilised items.

Step 7: Dry Thoroughly

  • Place sterilised items on a clean, dedicated drying rack and allow them to air dry completely.
  • If your chemical steriliser container has a lid or built-in drying function, follow instructions to maintain hygiene while drying.

Step 8: Store Safely

  • Once dry, store bottles and parts in a clean, covered container.
  • Use within the recommended period stated by the steriliser manufacturer (often 24 hours at room temperature).

Extra Tips

  • Inspect all bottles, teats, and valves for cracks or discoloration regularly.
  • Always follow the chemical steriliser’s instructions carefully for dosage, timing, and rinsing requirements.
  • Cold water chemical sterilisation is especially useful when boiling or steam sterilisation isn’t practical (e.g. travelling).
