ng
Mineral Buildup
One c o m m o n problem with steamers is mineral buildup caused by the high
mineral content in many municipal water supplies. Mineral residue inside of the
internal pipes and heater can cause intermittent steaming or in severe cases no
steaming at all.

T h e b e s t w a y to avoid this is to use de-mineralized or distilled water in the unit.
The procedure below can be used to clear mineral buildup. If you are unable to
use de-mineralized or distilled water w e recommend you use this procedure
monthly t o help avoid mineral buildup.
1. Turn the unit off and unplug the power cord.
2. Unscrew and remove the hose from the hose connector on the top of the
u n i t .
3 . Remove the pole from the unit.
4. Remove the water tank from the main unit and drain any water in the
unit.
5 . Make a mixture of 50% vinegar and 50% water. I n most cases 1 cup o f
this mixture will be sufficient.
6. Slowly pour the water-vinegar mixture into the hose connector.
a . If the internal piping is only partially blocked by mineral
buildup, the water-vinegar mixture will soon start f l o wing out
of the water intake hole. If this happens proceed to step 8.
b. If the internal piping is completely blocked, continue t o pour
the mixture into the hose connector till full.
7. Pour the water-vinegar mixture into the water intake hole until full.
8. Let stand for 40 minutes.
9. Drain the water using the drain plug.
10. Pour clean water through the hose base and water intake hole until the
vinegar smell dissipates.
11. Reassemble the unit and operate normally.
If the procedure above does not return the unit to normal operation, the unit may
need servicing.
