Calcium build-up in mold cooling passages.

[JV627]

Hi,

Does anyone have a solution for removing calcium build-up in a mold's cooling passages?

We've tried flushing with CLR but with very minimal success.

Thanks

We use white vinegar for removing calcium, and it works pretty well. CLR has never worked for us.
