How to clean this off glass tile?

[tradewinds]

Looking for a way to clean off this rock hard stuff that leached through from the new plater on the waterfall.

Builder superintendent guys said to use mauriatic acid and brush on but wouldn't that etch and dull the class tile?

No easy way to remove it.

Diluted muriatic acid should not etch glass tile. It will weaken the grout around the tiles.

You will need to use some type of acid solution to soften the efflorescence and scrape it off.

Try using 3M Pads with SR3 as described in Waterline Scale Removal - Further Reading

I just got rid of some scale with diamond polishing pads. They’re all over amazon. They will remove the scale but can also ruin the finish of the tile. I just ordered some high grit ones to see jf the result is better.
