How scunci steamer work?

Question:I have a scunci steamer that no longer working. It builds up steam but nothing goes out when I push the button. Searching for a sketch illustrations of this thing found NOTHING.
Any one knows the answer? Thanks.

Answers:
Have you been using plain tap water in it? If you are, then you probably have a calcium buildup. You can use lime-away or CLR and soak the part where the steam is supposed to come out. Take a toothpick and clean out the opening.
