| My iron gets gunked up easily because in addition to my sewing, my daughter starches her work shirts every day and the starch builds up quickly on the iron. I have used a variety of different methods to try to keep my iron clean, but it seems that the best I had tried so far (until now) was the Rowenta iron cleaner. Although convenient, it is very expensive - even with a 40% of coupon. So, I decided to Google and You Tube a "clean iron" search. I tried a few different things, but the absolute best (and easiest) is this. I also have used this method on both hot or cold iron and it works great!
I put a little baking soda in a small container and keep it in my sewing room. I also bought a small bottle of white vinegar that is kept just for the sewing room. Dip an old towel in the vinegar and then in the baking soda. Rub it gently over the iron and all the gunk will come off like magic! You may need to do this a few times or rub a little harder on any stubborn spots. After, you can just iron a clean spot on the towel, or wipe with a damp cloth to remove any vinegar or baking soda that remains.
This is MUCH cheaper than commercial cleaners, does not involve any chemicals, is easy to use, and works BETTER than the commercial cleaners. Give it a try!
