I decided to try 4 different methods:
Baking soda & Hydrogen Peroxide
BAKING SODA & HYDROGEN PEROXIDE
I was pretty confident the baking soda & hydrogen peroxide method would work because I’ve used it with success before on MANY things! (How To Clean Your Flat Iron; New Life For Old Cookie Sheets; My Kitchen “Miracle” Cleaner.)
Unfortunately, while it worked well at CLEANING the iron…it also got in all the holes of the iron plate and was NOT easy to get out. Even after using the “steam” setting over and over, most of the holes remained plugged up. I finally got them clean using a Q-tip dipped in hydrogen peroxide.
The toothpaste, as you can imagine, had a very similar outcome. Although my iron smelled minty fresh after scouring it with toothpaste, it didn’t actually clean as well as the baking soda and hydrogen peroxide AND it clogged the holes.
The salt method didn’t have the same clogging issues as the baking soda and the toothpaste, it just didn’t seem to do much in the way of real cleaning either. But, to be honest, I’m not sure if I did it long enough because I was beginning to get frustrated at this point.
MAGIC ERASER SPONGE
That left the magic eraser sponge, which is called MAGIC for a reason! No issues with clogging and it cleaned the iron like a champ. Just wet the eraser and rub the iron plate until it comes clean.
