The two theories I've heard floated around as to why the OMER's were so much worse than the others where:

1- The release agent used in the molds caused it.

2- Inferior glass used in the mask as a cost savings measure.

After the plastic roller pins I found in my Bandit I'm more inclined to believe the second one these days.

I have, on occasion, had scuba students who would exhale through their nose during their entire dive, which would cause excessive mask fogging, but since we don't breath off of a regulator at depth while freediving this shouldn't be an issue- at least it never has for me.

The best luck I've had with a mask right out of the box is with Cressis sub. I have also found that new Clear silicone masks are easier to clean than new Black silicone masks- at least the ones from the major scuba companies.

Besides toothpaste, soft scrub, spit, kelp, potatoes, and commercial defog I've found that soaking a new mask overnight in a grease fighting dish soap to be quite effective as well as running one through a dishwasher- as long as you don't leave it in for the drying cycle.

Still, you can't go wrong with the Micro mask.
