To prepare your diving mask for use, follow the manufacturer’s guidelines.
- Scrub new masks to remove the protective chemical coating.
- If you do not remove the protective coating, you will not be able to defog the mask effectively.
- You can use an appropriate cleaner to clean the inside of the glass in order to remove the coating, although this might take a few attempts.
- Adjust the strap on the mask for a comfortable but not tight fit.
If your mask mists up while underwater, you will get lots of practice to clear this in your confined water session.
