Polished white limestone floor got flooded. Some areas with subtle beige stains, couple of bits where colour from a wood basin support has stained the floor dark brown.

Any ideas?

I would also like to know what may be the best option for removing stains from limestone/travertine especially around cooking areas which have the usual wine and food stains.

Sorry to ask but are you sure it is polished WHITE limestone because under normal circumstances white limestone doesn't polish that well!

Not high shine polished, but white and as smooth and close-textured as I've seen.

Pre wet the stone, apply Heavy Duty Tile & Grout, allow to dwell, apply honing powder using a rotary fitted with a soft to medium brush, scrub it in then vac and rinse.  If it is all ok go over the floor again using a pad and 400 grit powder, then if necessary 800 grit powder,

Max, I have just had a very similar problem to yours this week, a polished white limestone with staining. I used LTP Grimex and it came up a treat, try that.

[Kev Martin]

Max

LTP Grimex will work as well because it is also an alkaline as is Aqua Mix HDT&Grout the only difference is Grimex is 11.5 ish on the pH scale so HDT&G is stronger but apart from that with the method I suggested the honing powder adds Mechanical Surface cleaning as well as a chemical clean.  If you prefer Grimex we are about the cheapest in the Country for LTP Products and sell more of it than any other independent retailer in the UK.

My only concern was honing powder could lead to needing a repolish??

I assume Max means smooth but non-reflective.

I disagreeumption as well hence the suggestion of Honing Powder!  Probably 400 or 800 grit

That's right. Is this stain likely to be shallow enough to remove with honing powder? I had been wondering about something to soak in & react chemically with the stain, sodium percarbonate to oxidise or sod met to reduce. Anyone tried this approach?

That's why you pre wet and use a high alkaline as well so you have chemical and mechanical action to remove. If the method does not work and the staining is deep then you may need to use a poultice.

Sodium percarbonate can be successful but mainly on organic stains.

We have a product called Hannafin Oxyklenza that contains perc.

Great on urine, wine and grease spots. Can be used dilute as a cleaner of mixed as a paste for stain removal.
