Medela pump in style advance TUBING?

Question

So..i sterilized the tubing today, since i haven't done it so long. I know the tubing doesn't really come in contact with the milk, but i figured it wouldn't hurt. Anyway, I used one of medela's microsteam bags. After it was done i hooked it up and let the pump run some to let it dry a little and then i hung them to be sure to completely dry. Well a couple hours later i went to get them and on the OUTSIDE of the tubing there was almost this chalky type residue(that is just the best way to describe it). Not tons, but i have never noticed it before...Is this normal?

Answer 1

Its from the water.  Nothing wrong though.  You can contact Medela and they will replace the tubing for free.

Answer 2

yup totally normal, same happened to me.

Answer 3

It's discoloring because you sterilized it.

Mine did the same.

Answer 4

Same thing happened to me...I do remember reading in a pamplet that is what happens with the tubing and that it is fine...

Answer 5

Yes! The same thing happened when I steam cleaned my tubing.  However I have no idea what caused it.  Sorry!

Answer 6

the chalky residue is caused by minerals in the water/steam! it is completly ok, try to get it off though cause it can keep building and clog it up! :)
