  1. 1

    Put on a pair of rubber gloves and set up to work in an outdoor area.

  2. 2

    Apply a coat of Armour Etch onto a cotton swab.

  3. 3

    Spread the Armour Etch evenly on both sides of the lenses using the cotton swab.

  4. 4

    Let the cream remain on the lenses for about five minutes.

  5. 5

    Rinse the lenses in clear, warm water to remove all of the Armour Etch cream residue.

  6. 6

    Dry off the lenses with a nonabrasive towel. All traces of the scratch resistant coating should now be gone.

Tips and warnings

  • Armour Etch will ruin lenses made of glass, so this method is not intended for glass lenses, only plastic. If you are unsure as to whether your lenses are made of plastic or glass, you can place a very small amount of Armour Etch on a small area of the lens to make sure that it is safe to use.
  • Armour Etch contains hydrofluoric acid, which is very harmful to the skin. You should undertake these steps in an outdoor area, if possible, as you will need plenty of ventilation. Armour Etch is irritating if inhaled, so it is advisable not to work indoors with this product.
