You will need a mild acid, such as vinegar, breaking down the lime, or vitamin C or lemon juice. all family friendly and should not leave any stains on your cloth after clearing with water afterward.

My mother would set it in a thin layer of white vinegar and let it soak overnight. This always worked for her.
Place several brown paper grocery bags on the ironing board. Next heat iron, run iron over a block of plain wax/paraffin then iron it off on paper bag and your iron is clean.
You could try wax paper if you do not have
a block of clear wax.
This always works, just be careful. I use this
method. (09/18/2007)
