We've just had our new tiles fitted and grouted, but they have some nasty grout residue on the surface. The tiler will be returning later on, once the grout has set, to give them a couple of washes .
These are natural slate/quartzite, but are maybe acid-sensitive. We had purchased some fila Pre-grout sealer to be used, but the tiler has not used this.
Is there anything that we can use to remove the haze before sealing?
I have seen that there is the Fila PS87 Pro. Would this be suitable?
Thank you in advance.
