Preparing the descaling solu-


Citric acid, available at some drugstores,

or 100 % bottled lemon juice are used for

descaling. Choose either one to use, and

prepare the descaling solution.
<For using citric acid>

Dissolve 3 teaspoons of citric acid and 2

1/2 cups of lukewarm water in a suitable

container, and stir well.
<For using lemon juice>

100 % bottled lemon juice can be used

for descaling. Use only 100 % bottled

lemon juice with no pulp (strain juice if

necessary). Combine 1/4 cup lemon juice

and 3 cups of lukewarm water in a con-

tainer large enough to hold the Humidify-
