MONTHLY MAINTENANCE
The Miracle Steamer utilizes an open steam
Generator. Water sprayed onto the Generator
surface flashes into steam immediately,
but the minerals in the water stay on the
Generator surface. A small amount of calcium/
mineral deposits are needed for proper operation, but a buildup of excessive calcium/mineral deposits causes poor steaming efficiency
and excessive moisture (wet steam), which
will eventually severely hinder the steaming
action.

and/or scraper to loosen and remove
the excessive calcium/mineral deposits
from the Generator surface.
5. Take a wire brush and clean out any
buildup from the 28 Steam Ports
(26 vertical and 2 horizontal) of the
Generator (Figure 9). Remove the
loose buildup, wipe the Generator
with a clean, damp cloth, and reassemble the unit.
NOTE: If deposits are still excessive and/
or difficult to remove, refer to Steps 6
and 11.
6. Pour delimer solution (not supplied)
onto the Generator surface. Follow the
delimer manufacturer’s instructions for
proper mixture and use.
CAUTION
If a chemical cleaner is used, be sure it is
safe to use on cast aluminum. Observe all
precautions and warnings on product label.
7. Using a sponge or a dry towel,
remove the delimer solution from the
Generator surface, then rinse with
clean water.
To ensure proper steaming characteristics,
some calcium/mineral deposits must be present on the Generator surface. If, during cleaning, the surface does become free of calcium/
mineral deposits, add plain tap water to the
surface and allow it to boil off. If necessary,
repeat this process to formulate a thin coating
of calcium/mineral deposits.
READY
Steam Ports

Figure 9. Monthly Cleaning
In soft water areas, it may be necessary to
add a small amount of lime to the Generator
to season it. This will ensure proper steaming
characteristics by producing a thin coating of
calcium/mineral deposits on the Generator
surface.
Seasoning mixture consists of 3/4 ounces
(25ml/ 25cc) baking soda, 3/4 ounces
(25ml/25cc) lime mixed with 1 quart
(950ml/950cc) of water. Stir mixture and pour
1/4” deep onto the hot Generator surface.
After mixture is converted to steam, the
