How to remove water stains on bottles after cleaning with the Momcozy KleanPal Pro Baby Bottle Washer & Sterilizer|BS03

It can be greatly frustrating when the water stains remain on bottles after cleaning and drying by the BS03 washer and sterilizer.

We’ve carefully analyzed the issue of water stains on the bottles after cleaning and have outlined potential causes along with solutions for your reference:

1. Improper Bottle Placement

Cause: Bottles incorrectly positioned, especially if the neck is not aligned with the spray jets, can prevent water from flowing into or out of the bottle properly. Consequently, there may be only a trickle of water to rinse the areas requiring cleaning, or it cannot drain smoothly from the bottle, resulting in water stains.

Solution: Place bottles correctly following the user manual, ensuring the neck aligns with the spray jets.

2. Overloading the Machine

Cause: Overloading or placing too many items at the bottom can obstruct the spray arm's water flow, preventing water from rinsing the areas that require cleaning, or it cannot drain smoothly from the bottle, resulting in water stains.

Solution: To ensure optimal cleaning performance, refrain from overloading the machine and make sure the spray arm has ample clearance to effectively spray water and rinse all areas that require cleaning.

3. Improper Detergent Usage

Cause: Using excessive detergent or non-specialized detergents may leave residue, causing water stains.

Solution: Use one Momcozy specialized detergent tablet per wash for optimal results and complete dissolution.

4. Hard Water

Cause: High levels of calcium and magnesium in hard water can form spots or scales on bottle surfaces.

Solution: Use distilled or softened water for cleaning. If scales persist, consider using a baby-safe descaler regularly.
