I’m not having any luck getting the haze off some porcelain mosaic tiles (1” by 2” rectangles).
The grout is black, the tiles are white. I’ve tried the concentrated grout haze remover with scotch brite scrubber, netting unsatisfactory results. Any advice appreciated, Thanks

Black is absolutely the worst color to clean up. Bright red is a close second. How old is the grout? should be able to clean it properly after 24 hours.

I cleaned most of it off the first day. The next day I wiped more of it off with a dry towel. The next day I tried the grout haze remover.
Try white vinegar, straight up on a clean sponge.Spheramid Enterprises Architectural Woodworks

Thanks for the tip. I've got a gallon of it from the mold recipe someone else here mentioned.
Think a buffing tool on a drill would work, if this doesn't?
I don't know. Buffing tool is a broad spectrum term.
Sponge buffers used on autos with Maguires Mirror Glaze and products like that , that look kinda like egg carton foam , would be about as abrasive as I'd want to try.
Unlike sanding wood, I'd start with the FINEST abrasive/chemical, and work back wards to what gets it done, then work BACK up to polish. If that makes any sense.Spheramid Enterprises Architectural Woodworks

I was envisioning vinegar on the buffing pad as a possibility. I'll try the vinegar first though.
There is an orange nylon sponge that is very effective when used with white vinegar.
Maybe try VERY diluted muriatic acid?
I have used the 'Zep' brand grout cleaner with success, I think it's weak muriatic. I got a little desperate to clean off the haze on one project, and used Comet cleanser with good results.
I once called Laticrete about removing a stubborn haze and the rep there told me to use dishwasher detergent. make a paste out of it and scrub with a scotch brite pad.
it worked well enough with a lot of elbow grease
Rent a commercial floor buffer from your local tool rental agency, and buff the floor using the green Scotchbrite discs. (White is too fine; black is too coarse.) The abrasive in those discs is too soft to scratch porcelain tile but it will peel that haze right off them in a jiffy. Vaccuum up the dust with your shop vac, damp-mop twice with fresh water, and you're done.

I'll have to give these all a try, starting with the simplest . Thanks for the tips,
