Anti-fog

A drop on the lens before the dive. Spit works, the bottle works better, and neither works until the new-mask film is burnt off.

01 What it is for

A mask fogs because warm, wet breath condenses on cold glass. Anti-fog leaves a film on the inside of the lens that stops the condensation forming droplets, so the glass stays clear for the session. A fogged mask is a dive spent seeing nothing, and on a Moroccan point where the fish comes once, that is the fish.

Saliva does the job for an hour; a commercial anti-fog or baby shampoo does it for a session.

02 What to look for

What matters:

  • A gel or liquid meant for dive masks; commercial anti-fogs are cheap and last months.
  • Baby shampoo, diluted, is the classic substitute: a drop rubbed in, rinsed once, and the mask is clear all day.
  • Spit works, and works less well as the day goes on.
  • Toothpaste is for the new-mask film, not for daily use: it is abrasive.

None of it works on a new mask until the manufacturing film is gone. Burn it off with a lighter flame moved lightly over the inside of the glass until the film clouds and clears, or scrub it hard with non-gel toothpaste, before the first dive. Then anti-fog each session.

03 Fit and sizing

One drop per lens, rubbed over the whole inside surface, rinsed once in the sea before putting the mask on. More is a film you look through.

04 Care

Keep the bottle out of the sun and closed. Apply on a dry lens for best effect.

Common mistakes

  • 01 Anti-fog on a new mask that has not been burnt. It fogs anyway and the diver blames the product.
  • 02 Too much. A greasy film that blurs everything.
  • 03 Not rinsing. Eyes streaming at 10 m.
