Rust Spots on Texas Cream Limestone.

[polkafan]

Hello,
I work in masonry and we recently installed a Texas Cream fireplace surround. I cleaned the stone with a damp cloth to remove all of the left over debris lest from sawing. It seems though after my cleaning a rust stain emerged. I was told by the company that made the surround that that was normal and that that stone will do that. But the problem is is that it looks terrible. Is there anything that I can do to remove the stain?
Thank you for any response.
Jenny

it depends on the finish of the stone. a carpet cleaning rust remove will work great but it will etch the stone, and it will have to be refinished to match the rest of the stone. thats probably the easiest way to do it....for a pro

Hi Huligar,

Is this an endorsement from experience? Looks promising.

Thanks

This is not an endorsement what so ever.
John told us of this a few months back, the little sample that Only allow me to run one test that came out pretty good for a food stain on marble. I can not endorse this item, because I have not done any extensive research in a uncontrolled environment.

	Marble MARBLE: CHARACTERISTICS This standard includes general information on the characteristics and common uses of marble and identifies typical problems associated with the material. INTRODUCTION Marble is an extremely hard, metamorphic stone composed of calcite (CaCO3). It is formed as a result of the recrystallization of limestone under the intense pressure and heat of geologic processes. The effect of this process is the creation of a stone with a very tight crystalline structure and small but definite porosity. Because of its structure, marble can take a very high polish and is a very popular decorative stone for architectural and sculptural uses. The limited porosity of marble, especially polished marble, makes it less vulnerable to the leaching effects of water. Calcium carbonate, however, of which marble is composed, is highly susceptible to attack by acidic agents. Marble is readily dissolved by acids, even very dilute acids, however the actual results of acidic exposure will vary with the nature of the acid. Chlorides, nitrates, sulfates and other chemical compounds react differently with marble and produce various by-products, which have a wide range of solubility and impact on the durability of marble. For this reason, it is always important to determine the exact type of pollutants causing marble deterioration. Marble itself can be of two types, one composed of calcite and the other of dolomite. Dolomitic marble is much more resistant to acid attack than calcite marble. The color of marble ranges from the brilliant white of calcite to black, including blue-gray, red, yellow and green, depending upon the mineral composition. TYPICAL USES Marble has many decorative and structural uses. It is used for outdoor sculpture as well as for sculpture bases; in architecture it is used in exterior walls and veneers, flooring, decorative features, stairways and walkways. The way in which the stone is used may be a factor in limiting or controlling the severity of exposure. The use or function of the marble may also affect the feasibility of applying certain treatments, but type of use is not the primary factor in the major types of deterioration and damage to which marble is susceptible.

Thanks,

I'll get some and look for a test site.

If you can report your findings, it would be a great help to this stone community. I must warn you, it smells like bad eggs.

No lies about the eggs...hits you like a punch in the nose...

I recently used this with a custy...they were super satisfied. Didnt even wait the full 5 minutes as directed lol ...too scared the purple would sink in the stone

AFTER



tried a second application but that was the best it managed.
