It's just like using vinegar to clean a coffee maker or a steam humidifier. It softens the calcium deposits that can gunk up the vents or cause particles to break loose and cause leaks where once water was kept tight.
Pour half water, half white vinegar into your iron. (Vinegar will not hurt your iron). Fill the iron, turn it on and let
it sit for an hour. The auto-shut off will turn it off eventually, this
is ok, just let it sit to soften the crud.
Afterwards, take the iron to the sink, hold it upright and shake it
gently to loosen the crud. Then turn the iron upside down and pour the
vinegar out of the iron. Fill with water, shake and pour the water out. If you've never cleaned your iron before repeat step #1 two more times.
Add white vinegar to the iron, fill it to the top. Turn the
iron on high, turn the steam to high and hold the iron horizontal over
your sink, as if you're ironing.
Let the steam vent out until the iron
is about half empty of vinegar. Then turn the iron upright, shake it
gently as before and turn it upside down to pour the remaining vinegar
out of the iron.
Fill with plain water, empty, fill with water again and repeat the
process of venting steam until you're satisfied all the vinegar is out
of the vents. Now you've just added another few years of service to
Note: This is the cutting board my husband made for me. A tupperware colander fits perfectly. I place a plastic cutting board on top of the colander and slide the veggies into the bowl of the colander as I go.
