Frequently Asked Questions (FAQs)

1. What are the ways of defogging a mask?

Glycerin Soaps and Dishwashing Detergents. Glycerin soaps and dishwashing detergents can be used the same way as baby shampoo. Put a few drops on the inside of the mask, rub them in, and rinse briefly. If a mask leaks, it is possible that the water will carry whatever defogging agent is used into the diver's eyes.
