Removing stubborn white residue off mask

[Comm]

So which product ultimately worked? The Cerium Oxide?

I actually have the same thing going on with my AA Frameless that I bought 10 years ago. It's my pool mask and have never been able to get it clean. I have sort of just given up on it

Yes Cerium Oxide is the winner for my case.

I don’t want one, gave up on them for SP D mask that I can replace the lens in, but it’s what you’re looking for, even if you don’t want to admit it.

Like I said in up thread, I have 2 already and they are already broken in to plaster my face like Remora.

I’ll be going back to Indonesia on 7 September, leading a group of 8 to Banda Sea. So, I have an incentive to get it done before I leave.

My guess is CaCO3.

To impress your clients!! LOL.
Calcium carbonate is readily soluble in vinegar!! Common sense.

How much did you spend on products Dan? Good masks like my all time favourite, Holls M 1 are not too expensive, I just bought a 'knockoff ' of the M1 as a spare mask and was surprised how good it is. I did enjoy reading about the different products used in in this topic though. Please tell us you purchased a new mask and what you bought.

The M1 is my mask of choice as well. What was the knockoff?

I think this is clear enough for me.

Dude, you're going to have to speak to your mum, damp cloth around your finger and into the cerium oxide

I’m hesitant to use HF as it would dissolve glass.

Dude, so don't say all my shower screens, toilets, baths, ceramics, glassware... but boy have they sparkle-arkled

Maybe not so much at the moment, been busy so no picture

and here I'll lend you my shed build helper Wild Turkey for some intestinal fortitude so try it

Dude, give it up, invest, get yourself some of this stuff, it's, what is it, it's magnificent

That's it I'm off to drop some mask glass in some vats of hydrochloric acid, ha

Ha ha ah ah ha ha ha ah ha ha ha ha ha!

This topic has gone way off topic as it is.

Around $40 for the Cleaning Vinegar, Bon Ami & Cerium Oxide. They are useful for cleaning up other household items so I don’t mind spending some money for these stuff.

bargain in the name of science

I'm glad it worked for you!

I don't know much about polishing glass...just my research for the one experiment polishing that windshield scratch

a couple of observations...
In every case I found in my research, teh polishing was done using a polishing wheel (wool or synthetic felt disk) or a rag if by hand, not a brush
so I wonder if you'd have better results with a rag.
and keeping in mind that you want to maintain a flat surface on the glass
If you can remove the glass from the mask, then you could lay it on a flat surface and long board it with a rag, similar to how a body shop does wetsanding for a car's paint....i'm thinking a rag wrapped around a sanding block or a block of wood, using the wet slurry compound. I wonder if that would make for faster and more accurate work

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.
