Grout haze

[LydiaEdwardianHouse]

We have just laid and grouted a patio but can see a slight haze. They’re porcelain tiles and were treated with LTP beforehand. Any tips on how to remove the white sheen / film? Pic one of grouted area, pic two of non grouted

Maybe try.
Gloves.
White spirit and rag.

If you use water it an endless cycle with haze every time it dries
