Your scuba or snorkel mask is one of the most important pieces of equipment you will need to enjoy the underwater environment. It is usually the first piece most diving buy and one piece of equipment that if not the right one can make your diving experience miserable. Below is some of the most frequent questions and solutions to common issues.How long does a scuba mask last? A good quality mask such as one made with tempered glass and high grade silicone has a very good lifespan. A mask that is well taken care of and stored properly will often last 10 to 20+ years. How to care for and store a scuba mask? Masks will need regular washing with warm water, a mild soap such as dish soap and a soft brush or cloth. Rinse with fresh water, dry and store in a container or case in a cool, dry place away from direct light. The silicone mask strap and skirt can seem an attractive toy to animals so make sure it is not accessible to pets.My scuba masks always gets foggy, how do I make it stop? New masks all need a good wash before use to remove any manufacture oil or dust. Dish soap, hot water and a soft brush or cloth, wash and rinse a few times on the inside of the glass. This process also needs to be repeated on a regular basis, the cleaner the inside glass is the less the fog will stick to it. Once clean a commercial de-fog such as Sea Gold or Sea Drops will help keep things clear.The silicone around my mask has turned cloudy and yellow, what can I do? Crystal silicone will naturally take on an opaque or yellowed appearance due to UV in sunlight as well as exposure to chemicals such as those found in make-up and sunscreen. This is a cosmetic reaction and does not degrade the ability for the mask to make a seal. To prevent or slow the process make sure to wash your mask regularly, store it clean in a container away from sunlight. Another way to prevent this is to get a mask made with colored silicone as his will protect it from UV.My scu
