English Heritage & cleaning stone floors with milk!

[RealisticSketch]

I am about to install stone floors in my house and have read a few threads on here about what a pain they are to keep clean (oo-er too late now!). But I came across this:
www.english-heritage.org.uk/about-us/search-news/pr-spring-cleaning/
I would love to think my floors could be lovely and clean with this inexpensive method... has anyone been brave enough to try it? Spilt milk is usually avoided like the plague (did that in a hot car once , so this seems so counter intuitive but they tested it so...

I have read this suggestion too, but always been highly suspicious of it. I suspect it would stink. Maybe the milk is supposed to make it shiny or something. If it is a new stone floor, I would get definitely it sealed as soon as it is laid, then just clean it in accordance with manufacturers’ (stone and sealant) instructions - obviously, this will depend on the type of stone, as different types of stone will be damaged by different things. Beware of steam mops if you do seal the floor, as they will take the sealant off.

Could to know about the steam mops.
Yes, I don't know how it doesn't smell... but I found the article after I heard an interview where the person was saying it worked great. The casein gives it protective layer and makes it shiny apparently. Really curious but hoping someone more brave than me would have tried it first.

good to know

If it’s a new floor, perhaps just try the milk thing on a sample ( stone and grout) if you’re dead keen. Then you can report the results of your experiment to the hive ( unless someone else has already tried it).

We used to use milk to clean rubber plant leaves. It didn’t smell. Try a small piece of stone and see? Can’t say that I’m sold on the idea.

I’m not sure about milk. But that’s a fascinating link. We used bread to rub out chalk and oil pastels in art class, and I remember my granny polishing the brass with ketchup.

Oh yes! I have heard of the ketchup for brass cleaning. How lovely you remember your gran doing that.
I am sure there will be broken bits I could test it out on. I think it is the fact that it is such a mad idea (who grew up without their mum bring very responsive if you spilt milk!? 😆) That I need to know. [Grin]

In the interests of science - can you do a bit with full fat, some with semi skimmed and some with red top? I’m guessing full fat would be needed.
(I’m too invested in this now!)

English Heritage said skimmed was far better than half or full fat, maybe the fat content would be the bit that would go rancid and smell?

I am also invested and need to see this through.
