Little lines or grout removal from face of porcelain tiles

[PULLMYFINGER]

Hi,

Finished grouting my porcelain tiles down stairs loo, on Friday just gone and cleaned them up just before i left for the weekend, They looked spot on whilst a bit damp came back yesterday and in the pits of the face of the tiles where the surface is uneven there's little lines of gout.


I've tried scrubbing with water and a kind of rough scourer pad thing, and though its slowly working is there any thing quicker i can use to help. I cant be the only person this has happened too. They looked perfect on friday just as i'd finished, the tiles are porcelain to should be able to withstand a canny scrubbing.

i know this question will have been answered to the death on here but there's nowt about porcelain tiles i can find

Thanks in advance
