Removing excess grout from quarry tiles

[tapir]

Hi

I am in the process of grouting my kitchen floor - which is quarry tiles on ply.
I am using Bal Superflex Wide Joint Grout in black. However, it is proving a nightmare to clean off the tiles, even if wiped off immediately. Has anyone got any tips/products I could try?

Thanks very much in advance!

I used this on quarry tiles and it worked. It's a weak acid solution

Might want to test HG 'Extra' cement /grout film remover. Again. its acid based so be careful

Thanks to both of you.

Will have a go.
