damage to glass tile "glaze"

[Ron Dunbar]

i have recently completed an installation of large format glass tile. the tile is manufactured by Porcelanosa, and this tile comes with a matte finish that the manufacture calls a glaze. my problem: i used white vinegar to clean up a light grout residue(which worked), but the vinegar lightly etched the "glaze" and has left some streaking on the tiles. i e-mailed photos to the factory techs in Spain, and after some days of research, they deemed the damage to be unrepairable.

does anyone out there have a solution? thank you for any advise you can give

I am skeptical that the vinegar made that bad of an etch unless the tile has a glaze that really shows everything.I would try cleaning with a little neutral cleaner and ammonia in a bucket of water,maybe use a stiff brush then use a towel to dry it and see what you've got.But i guess they would know better than us not having seen the tiles.

wash the rest of it with vinegar to even out the finish.

Welcome, Ron. :)

Can you give us an exact name for that tile?

Glass tile gives us plenty trouble hereabouts without now having a "glaze" that is sensitive to vinegar. Like to know just what that is when it comes up again. :shades:

Try making a paste with baking soda and water. Scrub the glass tiles with this using a scotchbrite pad. Then rinse with clean water and a towel.

thank you all so much for your suggestions, i am working on scraps from this job. the "glaze" on this imax glass tile is not fired on. it is some kind of sprayed on matte finish. it is pretty delicate and can be easily scratched. i will try to get the factory techs to reveal the composition of this coating and the process used to apply.

thanks again and keep the suggestions coming!

This is good to know and could cause a postential problem for us Eco types. I actually clean with vinegar and water rather than the usual spray cleaners. Good info.

Good luck with that.If possible i would just redo the bad ones,you would never be able to duplicate a factory,probably baked on finish,if they would even tell you how,or give you the product.
