How to Cure a SCUBA Mask

How to Cure a SCUBA Mask
New diving masks are often coated with a layer of oily residue. This needs to be thoroughly removed before the mask is used on a dive, because the oil functions as a fogging agent. It also attracts dirt and grime, and generally makes caring for a mask much harder. The process of getting all the oil off a scuba mask is sometimes called "curing."


Difficulty: Easy

Things You’ll Need:
  • Non-gel toothpaste Washcloth Dish soap Defogging gel
  • Non-gel toothpaste
  • Washcloth
  • Dish soap
  • Defogging gel
Step 1
Rub a dab of non-gel toothpaste around the inside of one of the mask lenses with the end of your finger. Be thorough and spend at least a minute at it. Repeat for the other lens.
Step 2
Wash the strap, nose and skirt of the mask with a washcloth and ordinary dish soap.
Step 3
Rinse thoroughly and allow to dry.
Step 4
Smear a thick layer of defogging gel onto the inside of both lenses before taking the mask on its maiden dive.
Step 5
Hold the mask so the outside of the lenses are pointing down, and pour a little water into it. Swish the water around so it picks up some of the gel, and pour it out.
Step 6
Put the mask on and go for a brief swim in a pool, lagoon or wherever it is convenient. This must be done immediately, before the mask gets a chance to dry out.

Tips & Warnings

Some divers say toothpaste should not be used on plastic lenses because it is abrasive. However, if you rub it around with your finger, and not a brush, it won't scratch the plastic. Note that you should never use anything more abrasive than toothpaste with a plastic lens.
