Post tiling issues with finish

[Dilalio]

Hi all.
Looking for some input and advice.
Recently had master bath tiled and now working on ensuite.
We are the plumbers and have used our Tiler.
Customer not happy with finish of dark grey matt porcelain tiles as they are water marking, have striations and don't have a uniform look when dried.
Supplier is pointing finger at the Tiler and has issued her with wax-off, deep clean and grout removal chemicals (Lithofin). We spent yesterday using the grout remover and while there was some residue which came off, there is still unevenness with the dried finish.
Is the supplier trying to pass off a poor product or are there things we can do to satisfy the customer?
My take, from my experience, is I don't trust the tile.
Any advice greatly appreciated.
Deano.

Have you got a spare tile that hasn't been used and conducted any water tests our grout cleaner reactions on it .

Yes. Customer did this to a spare tile and took it to the supplier who "apparently" cleaned it up, so we're told?

Who's done this again?

Grout around the end of the bath instead of cutting the tile to the right shape?

That's not a professional tiler lol

Looks like polymer residue to me , wax off won’t remove it.
You need a stronger product.
Try lithofin cement away to break it down , try on an inconspicuous area first and watch the enamel works.
