If the silver screw knob or shaker top appears to be stuck on the mill and you are unable to remove it, then corrosion may have taken place between the two metal parts. If this has happened, you will not be able to remove the top but will have to send the mill to
Customer Services for a replacement.
To avoid this happening again or with a new mill, always remove the salt section of a Combi Mill when refilling. Filling it while it is still insitu is when salt becomes trapped in the threaded part of the shaft and causes the corrosion.
To refill, always remove the salt section and fill with ready ground table salt. Apply a small amount of cooking oil (eg. olive or vegetable oil) to the thread of the shaft. Replace the salt section and shaker top and screw knob.
If you have any problems or further questions, contact Customer Services.
