When the pool was built I was told by pool company I’d need my coping tile sealed so it wouldn’t stain. They recommended a guy. 11 months after the pool was complete I had the coping sealed. Contacted the guy a few days later bc it was a thick sticky mess. Like Vaseline all over the coping. He came out and said he used a lot that didn’t absorb and power washed it off. It obviously ran down the waterline tile. Now every time it rains my white tile turns black. He came out again and used a pumice stone to clean the tile. It’s still turns black every time it rains. You can feel the wax coating on the tile. I know it was the sealing bc I never had this issue until it was sealed. Any chemical I can use to remove it or other suggestions?

Welcome to TFP! 
I don't suppose you would have any way of knowing what product he used so we could look up the ingredients?

Unfortunately it is a solvent-based siloxane (organosilicon compound) based material. These materials are incredible hard and resistant once they fully cure. My guess is that there isn’t anything you can apply to it that would completely damage the tile. You can try contacting the parent company’s technical support, show them your images, and ask if there have an y way of removing the material -

Thank you for the information. Someone suggested bead blasting. Any idea if that would work? I hate to spend the money of it won’t. Sounds like the tiles may need to be replaced. I would’ve never had the coping sealed had I know this could happen.
It looks like the protective nature of the sealer that ran down the waterline tile works well and the uncoated portion of the waterline tile gets slightly darker when wet from rain. Maybe make him put the sealer over all the waterline tiles so it’s not just the drip pattern it will protect the entire tile and look the same color when wet. I’d test one first to be safe if u have a leftover tile.

It really isn’t possible to advise beyond speculation here. If the sealer penetrated the surface of the tile, then glass bead blasting won’t do anything. You’ll probably wind up just damaging the tile. Call the manufacturer and seed if they have any ideas. Other than that, there’s not much that can be done short of replacing all the tiles which would be costly and likely result in other unforeseen problems.
As the user above noted, you could try draining down to below the tile line and then apply the sealer to the entire tile to see if it helps even out the look.
