COKE is the answer, it should be available world wide, u dont need to carry it with u on ur travels and is available on most if not all liveaboards and well stocked dive boats.
We all know what it does to our teeth, so think about what it does to that little film on the mask. Just a dribble in the mask, a rub with a finger and then leave it in there, overnight if its a new mask, or just on the first boat ride of the trip, 10 mins or so, to make sure and ... Gone. No fog. And no worries if u leave a drip or 2 behind for the dive. Im using atomics frameless mask too, and have no problems.

Here's another product specifically for removing the mold release agents from a new mask. SalClear comes in two different formulations. Salclear NP is just for hydrophobic substances (oils), while SalClear Aquasports is said to work on both hydrophobic and hydrophilic soils. On the website, they seem to be recommending that the two solutions be used together, sequentially, for best results. I haven't used either of these - just passing on the information.

i cant recommend the above advice enough, ives always had probs with masks-tried it all, spit [and mine deffo doesnt work so had to get others to spit in my mask] cleaning as per all the other advice, burning with lighter [altho i wouldnt do so had to find some brave soul to do it and altho it worked it didnt last] so on my new maks i was determined to get it sorted, spent £17 on the salclear box [do love things in little boxes] which had the two mask preps and defogger in and it is the best £17 ive spent. i did have to spend ages prep the mask [and had some fantastic support/help from salclear] used mask recently in swanage and it was brill, altho it started to fog a little on the surface [forget some advice bout cooling face down first] usually i start fussing at this point, but i decided to trust the guys at salclear, got in the water and could see bril [ altho it doesnt improve the water viz haha] for the first time. get it, dont listent to the other advice, as you could damage the lens
