Removing stubborn white residue off mask

[Dan]

Also I mentioned before that water is your friend
In the photo your paste looked dry to me. I was finding that when it's dry it introduces new scratches.

No, it’s always wet, muddy like wet. Occasionally I dipped the toothbrush in a cup of water and brushed the glass surface with wet toothbrush. If the area looked like too diluted with water, I added dry powder on it. Basically I swished around the mud over the stubborn white residue. Toothbrush is needed to reach the edges & corner where the tempered glass molded on to the silicone skirt.

Thanks to your suggestion of using cerium oxide. It works! I’m looking forward to my next diving destination, next week, to see Mola Mola in Bali & then heading up to Banda Sea to see schooling hammerheads.

using cerium oxide. It works!

When you get back could you update this thread as to if you had " More / Same / Less " fogging issues with the newly cleaned mask during your trip.

Have a great trip!

Nice report, Chris!

We pretty much did similarly & independently.

From now on I’m going to rinse & dry my mask after each dive. Don’t let the wet lens get dry under the sun. Wipe it dry after rinsing it.

I’m in Bali now. Tomorrow heading to Ambon for a diving trip to Banda Sea. We did 3 days of diving in Bali. Made a video for check out dive on 10 Sep, as shown in the following link:

Thread 'Video of Diving Gili Topekong in 10 Sep 2025'

Sep 10, 2025

We dove Gili Topekong, Padangbai, Bali, Indonesia on 10 September 2025 with Geko Dive Bali. We saw Whitetip Reef Shark, Day Octopus and Hawksbill Sea Turtle.

Went to Mola Mola cleaning station, but it was not there. Will try Crystal Bay tomorrow & Friday, weather permitting.

Very happy with the clean lens. No fogging issue. So I would say. Same, but things look much better without the white residues.

I've dived with the mask after the cerium oxide treatment. Like Dan, I had no problems with fogging.
