Impregnating granite tiles (highly absorbent - Chinaware)

Hello, I am looking for a high-quality product to impregnate strongly absorbent China granite floor tiles grey-pink polished. Can anyone recommend something? This is for initial treatment after installation. Possibly also with color deepener.
Regards

We used to use Lithofin Fleckstop for granite. I just don't remember which variant.

ok, thanks, I assume the experience was good? The local building materials dealer recommended Glutoclean (and it is also in stock), is that known or is that acceptable?

Lithofin stank like the plague, but it was good. I don't know Glutoclean.
