I have the this mask but have not used it yet. I read that it fogs quickly. What did you use to 'clean it' and not ruin the clear glass?
CHRIS P I've used mine for over 100 hours in the British Virgin islands and in Belize, so warm water only. I actually haven't noticed it to be any worse than any other low profile mask. I just use whatever common fog free I have in my bag at the time. I dont know if it's just coincidence, but I also keep it submerged for a moment before I put it on. It does however, seem to be much nicer in shallow water, rather than deeper. Around the 25 foot mark it crushes uncomfortably against the face, Still doesn't leak though. At this time, it's my favorite mask.
MARC R I haven't found this mask to fog up any more or less than any other mask I have used. I am very happy with the mask. Most dive boats have a bucket on board with water and I believe they use dish detergent to keep the mask from fogging. They also usually have some commercial mask defog on board. Ith all seems to work pretty good for me.
In a pinch just spit into the mask.
FRANK P Tooth paste. Do it 5 times
Best of Luck
DON B I had the same problem for quite a while with mine...much worse than any other mask I have owned.
One trick I leaned about but have not tried yet is to take a lighter or match and lightly drag the flame around the inside to burn off the oil residue that is causing the fogging.
Be careful not to leave the flame in one place too long. The silicone skirt is quite flame resistant, but you don't want to get the tempered glass hot or it may crack.
DO NOT do this if you have optical inserts (diopters) glued into the mask! I have the glued diopters, so was not able to try the flame trick.
The other technique often used is to rub toothpaste (not gel type) into the glass and all around the silicone skirt on the inside with your thumb, rub it around for a while, then rinse thoroughly, then repeat several more times. The idea is to absorb the oil and remove it with the mildly abrasive toothpaste. You can also alternate this technique with dawn dish soap. Be sure to get the entire inside of the mask, not just the glass. And be sure you have really rinsed out the mask before you put it on to avoid the stinging eyes.
It took me at least 10 cleaning sessions to finally clear all the fogging problems, but after that, it really is the best mask I have ever used.
DANIEL C Before first use wash the entire inside and outside of the mask with non gel tooth paste. Really work on the inside lenses then rinse well. Next put a few drops of dish detergent such as DAWN inside the mask and add some water. Rub the lenses and inside of the mask well. Rinse well, then rinse again just to be sure. Prior to my first dive of the day I apply a bit of 500 PSI anti fog then rinse. Before you put the mask on rinse your face if you to remove any sun screen or oil from your skin. This method works very well for me and I've had the Subframe mask for 6 years.
JAMES R Seabuff by McNett - they also make seal saver and other things. The SeaBuff will allow you to remove anything coating the glass and ensure your anti-fog is effective.
DARLA M I used toothpaste. I scrubed it inside and out, let it dry on, and repeated about three times. I was fine after.
RICHARD S We were on a dive vacation and we tried everything to reduce the fogging. It improved but the dive master has his own "trick". Not sure I recommend it unless you are totally frustrated with other solutions but I have heard of this technique before.
He took a lighter and with the tip of the flame let it blacken the inside lens of the mask as he moved it over the lens. He then wiped it with a rag and said all fixed. It was. I still use "cleaner" since for general care but that technique worked for us to get the new film off the lens.
