If you notice a brown deposit or what appears to be rust in your heating reservoir, this is actually lime scale (mineral found naturally in water). Your Babycook reservoir is made of stainless steel, so it cannot rust. To correct this, you’ll need to descale your appliance. Instructions for descaling are located in your product manual or on this site.
*Please note: Lime scale is not toxic to your infant
Instructions on how to descale your Babycook:
1) Fill the entire heating reservoir with white distilled vinegar and let it sit overnight
2) Pour out the vinegar
3) Run 2 cooking cycles with plain water
4) Repeat as many times as necessary until clean
*Be sure not to run the cooking cycle until the reservoir is completely clean. Otherwise, you are just "baking" the build-up onto the sides of the reservoir.
*Once the reservoir is clean, be sure to descale your Babycook at the first sign of build-up and also, ALWAYS use the mixing lid when blending (to prevent food from entering the reservoir).
Keeping the reservoir clean is much easier than trying to remove stubborn build-up.
