I find black masks seal better, but I have a heck of a time getting them defogged- compared to clear silicone masks.
I usually need to soak my black silicone masks in a bowl of degreasing dish soap overnight to get the lenses properly cleaned, and still defog it every time I go diving. With a clear silicone mask I just scrub the lenses with toothpaste and I am set to go.
This has especially been difficult with my OMER masks for some reason? I have used all the standard treatments that have worked on every mask that I've owned in the past 30 years- toothpaste, dishwasher cycle, store bought defog, spit, potato, kelp leaf, ect. Still, I get fogging whenever I use them.
I have a stack of other black silicone masks that I have owned for a long time and they are fine.
I am open to any new ideas to clean out the black silicone masks if anyone has one.
