For more stubborn stains or residue, you can create a mixture of equal parts water and white vinegar.

Dip the cloth or sponge into the vinegar solution and gently wipe the flat iron’s plates.

Toothbrush for Crevices:

Use an old toothbrush or a cotton swab to clean the edges and crevices of the flat iron. This is especially useful for hard-to-reach areas.
