A Lotta bit more than grout haze

[GreenTechAgain]

Hoping you guys can give me some advice about this job.

Not sure if I even what to do it if their problem is going to become mine.

This is grout that has been on the tile for about 2 years. It is a higher end rental and the current tenant is moving out. Property owner would like to have it fixed while vacant. About 1,500 square feet.

They are not concerned what the grout lines look like. Just want the grout off the tile.

Simple as black pads and acid?

Any advice would be appreciated. Thanks.

If that is ceramic tile,
Use Interlink's Viper Renew, an acid cleaner. Or any brand of concrete brightener, oxalic acid (Barkeeper's Friend) or phosphoric acid.

Avoid muriatic acid, it will choke the lungs outta you and stain any chrome and stainless in the room.

Apply your stuff by sponge to the grout slop and sip coffee for ten minutes. Use a wood stir stick to help break it up, then a stiff NYLON brush to finish it all off. Rinse the floor when finished, it is easy-peasy.

Did you try a razor blade?



Acid and black pad should do it.


Mask off everything.

star cleaner from home depot or lowes works for that. wet the grout lines first .

Do you ever wear your socks on the wrong side?

Since getting socks with L and R, I feel weird/wrong putting them on the wrong feet....

I know this doesn't have anything to do with your post but I commented to subscribe to the post to see the outcome....

You should be able to get the majority of it up with a 4" scraper. If you used a black pad, you'll end up with a dull finish and swirls. I am assuming this is travertine, that's what it looks like. You'll need to take it up to a higher finish to make it presentable

Sure that's not porcelain?

I see pattern repeat

I can relate. It just doesn't feel right.

I had an apartment complex that had that going on. I would do each one when it was vacant. I had to scrub with a red pad. I used a stripper. It took it off.
I got tired of dragging the floor machine up to the third floor. Thankfully they fired the manager and the new person had their own carpet cleaner.

Whoops. I edited my earlier post for ceramic tile only. If it is travertine, price it sky high and I'll drive down and refinish it. Dang it I need some Florida time and besides, Excellent Supply is just around the corner.
