I’m attempting to clean some blue stone slate in a club house. I attempted to clean an area with oxy blaster. Once the floor dried it left cleaning marks and a remaining white haze. I presprayed, scrubbed with a cimex and rinsed with a sx12 with plain water, both at 500 and 900 psi and fan dried and my results aren’t great. Any suggestions on cleaners and extraction ideas. I do have a 360 rotary with a hard surface brush that I’m thinking about using next time. Thanks for any input.

Most likely. I guess I’ll go back and use my xL360 with the hard floor brush. I’ll pre spray, scrub and then Flush slowly with it. Any other ideas in eliminating the efflorescence? I’m trying to post pics on iphone but it’s not allowing me too

You can clean this stone with acid side cleaners.

I doubt it's efflorescence.

Make sure you rinse well, especially if it has sheetrock dust on it.

Preaggitate with a soft brush will help too.
If you have a citrus solvent cleaner then use that.

Work small areas that can be rinsed before it dries.

Did it have a white haze before you started?

Sounds like it has a coating on it

Does it have any shine to it?

Is the the grout lines shinney?

Does it darken when wet?

Efforecence gets blamed for a lot. Although, if a coating was applied that does not allow vapor transmission, it will cloud, Also hinheat from TM will cause clouding

Yes it had a haze, I assumed it was fine construction dust. The room I cleaned was darker when wet and when it dried was darker than what wasn’t cleaned, but you can see water spots and cleaning lines once dried. I thought we can post pics on here, but I can’t seem to figure that out.

If it darkened when wet then I doubt there is a sealer or topical coating.

Sounds like you may have moved too fast on the rinsing and left spots & streaks.

If it has sheetrock dust on it then that can reactivate when wet and dries as you described.

Good news is it should clean up fine.
