Tips for Removing Grout Haze from Black Tiles?
Asked by CuriousCactus229
I recently installed dark grey sanded grout and thought I cleaned everything up properly. However, I still see some grout haze on my black tiles. I scrubbed the entire floor with a hard-bristled brush and soapy water, but that didn't help much. Should I try using pink paste, vinegar, or something else? I'm worried the haze is here to stay! Just to clarify, the grout was completely settled a couple of months ago. Here's a picture of the issue: https://imgur.com/a/liyFCuJ

From what I've done in the past, many grout kits come with a solvent for haze removal. It should be mixed with water, so check if you have one of those and give it a try.

You're unfortunately in a tough spot since it’s been a few months. The grout haze has likely chemically bonded. You might have to live with it for now, but keep in mind, once this happens, it’s a lesson for next time!

If you're looking at a strong solution, you could try muriatic acid, but this stuff is pretty intense. Always wear gloves, keep it ventilated, and dilute it a lot—start with 10 parts water to 1 part acid. Just remember, using it full-strength could damage your grout and tiles.

Check the sanded grout instructions for haze removal methods and also consult the tile manufacturer's guidelines. You want to be sure whatever you're using won't damage your tiles, especially their finish.
