I have white porcelain tiles installed in my bathroom. They appear to have significantly discoloured over time (first noticed a within a couple of weeks), and now appear in an off white / grey colour in sections. The tiles shown in the attached photos.
The tiles are in square sheets and the discolouring is aligned with each square tile sheet shape. I have tried intensive tile cleaner, with limited success, it may improve the discoloured tiles briefly, but within a week they are back to being quite visibly different.
Any advice / suggestions to fix, or similar issues experienced and how you resolved, short of ripping out and reinstalling, would be greatly appreciated.
Thank you!
