If the glazed porcelain tile has been etched by the acidic urine then it can’t be repaired. Normally if the glazed porcelain tile is cleaned timely and properly I would not expect it to etch the tile.
Hi there – my daughter was recently ill and was sick on some tiles from c1900 leading up to the house. I didn’t clean them straight away, but when I came to clean them, I’ve notice there is a very visible stain left. I have used detergent and water, tried baking soda and vinegar and have scrubbed the area but it is still not changing at all. Has this caused acid etching? Is there anything that can be done to restore them as they are the original Victorian tiles, or even out the colour? I think they are unglazed ceramic tiles but could be wrong – thanks in advance
What she threw up would be acidic. So it could have etched the tile. Normally unglazed tiles don’t etch, like glazed tiles. If it etched there should be a texture felt as it alters the tile surface. If it is a stain that absorbed into the unglazed tile then you might need to use a poultice that is normally used on stone to try to pull out the stain. You can experiment with an enhancing sealer that gives somewhat of a wet look and see if that even outs the stain.
Thank you Don, I was afraid of that.
Appreciate the thoughtful reply…
Does this answer also apply to glazed porcelain tile around the commode. There have been numerous dots of urine etching. Can this be fixed.
