Black Gulfstone Quartz with Mapei Ultracolour Black grout

[David Dudley]

Black Gulfstone Quartz tiles laid over Dural CI++ Matting over a year ago and grouted with Mapei Ultracolour Black

Grout has turned whitish/Grey and I would like to restore it back to its original clean Black

Which do you think is most suitable?

1) LTP Grout Stain Remover - will the acidity affect the Quartz?
2) Aquaseal Colour and Seal?

What would you guys use?
Thanks.
David.

Thanks cam_low

Universeal as I understand it - just seals existing grout without changing the appearance.

I am looking to restore the grout color to black and then seal.

Thanks.
