To clean baby water pipes glass (likely referring to a glass sippy cup or water bottle), you'll want to ensure it's thoroughly sanitized without using harsh chemicals that could be harmful. Here’s a step-by-step guide to clean it safely and effectively:

Materials:
=> Warm water
=> Mild dish soap (baby-safe)
=> Bottle brush or pipe cleaner (for narrow parts)
=> Baking soda (optional for deep cleaning)
=> White vinegar (optional for sanitizing)
=> Small brush or toothbrush (for cleaning nozzles and tiny parts)
=>Towel or drying rack

Steps:
Disassemble the water pipe: If the bottle or sippy cup has multiple parts (like a spout, straw, or valve), take them apart. This ensures that all pieces are cleaned properly, and no residue remains.

Rinse with warm water: Thoroughly rinse each part under warm water to remove any loose debris, milk residue, or juice buildup.

Soak in soapy water:

=> Fill a sink or bowl with warm water and a small amount of baby-safe, mild dish soap.
Submerge the glass, spout, and other parts in the soapy water and let them soak for 5–10 minutes.
Scrub with a brush:

=> Use a bottle brush for cleaning the interior of the glass.
=> For narrow tubes or straws, a small pipe cleaner or straw cleaner works well.
=> Use a toothbrush or a small brush for cleaning hard-to-reach parts like nozzles, vents, or grooves.

Deep cleaning (optional):

For stubborn stains or odor: Mix 1 tablespoon of baking soda with 2 cups of warm water. Use this solution to scrub the glass and other parts gently.

For sanitizing: After regular washing, you can create a mixture of equal parts water and white vinegar. Let the parts soak in this mixture for 10 minutes. Vinegar is great for removing bacteria and mineral deposits.
Rinse thoroughly: Make sure to rinse all parts thoroughly with warm water, especially if you used vinegar, as you don’t want any residue left behind.

Air dry or towel dry: Place the parts on a clean towel or drying rack to air dry completely. Ensure everything is completely dry before reassembling to prevent mold or mildew growth.

Tips:
Clean the water pipe daily, especially if used for milk or juice, as residue can easily lead to bacterial buildup.
If the water pipe is dishwasher-safe, you can run it through the dishwasher’s top rack, but check the manufacturer’s recommendations to avoid damage.
