HELP: Etching spots caused by juice spill

[Rafael]

Hi everyone,

Any idea on how to repair some spots (etching i think) caused from pineaple juice spill? Nothing really big, just a couple of spots (3/4 inch diameter each)

I would really appreciate your help

regards

Hi Rafael,

It depends on how etched the material is and what type it is.

Do this: run your finger over a polished section and then over the etched portion. Does it feel any different?

More than likely you will need the services of a professional familiar with the process.

Let us know and we'll tell you how to proceed.

Hi Steven,

It do not feel any change in texture, it seems like just a change in color, the spot is more clear than the rest of the piece.

I did clean the spill as soon as I could, so the the juice did not stay in contact with the marble that much (a few seconds), enough to change the color though :uhh:

What do you think?

Thanks in advance!

Rafael,

Is it possible for you to post a picture?

Do you believe the fabricator put an impreganiting sealer on the material?


What is the name of the material?


Generally it sounds like you had a film of some sort on the counter and it was cleaned pretty quickly. It may something as simple as a soap film.

It does not sound like the material is etched though. :yipee:

Steve,


Attached you will find a picture of the spot.

The marble is a sandy beige. I am not sure about the impregnator, but the porosity seems very low on the material.

Any idea on how to get rid of it? I have tried marble safe soap and water with no results, I think because it is not actually a stain but etching (smal though)

Rafael -

You are probbly right that it's etched. Pineapple juice is slightly acidic.

Try a polishing compound that's made for marble.

You can get some at www.mbstone.com

Hi Rafael, The stain shown in your pic will have to be removed with an old fashioned poultice. Go to a beauty supply and buy some 40% hydrogen peroxide. While wearing gloves mix baby powder and HP to a peanut butter consistancy and apply to the area larger than the original spot. Cover poultice with plastic wrap and tape edges down leaving a small area open for evaporation purposes. Repeat as required. If there is a loss of luster the you may need the services of a restoration pro. Michael of Stonehenge

Hi Rafael :)

It is difficult to see if the stone is polished or honed. The stone is definitely stained and needs a poultice as suggested. Try the poultice first, and come back here with the results. We can guide you from there.

it looks to me like it needs a poultice first to draw out the stain. the etch can be compounded out with marbacreme from stone care international...available at most Home Depots...it will take out most minor etching problems, like water rings....but if the juice ate a hole in the stone, this will need to be professionally polished out..

Just looking at the picture, if somebody had to ask me what it was, I'd put my bets on it being an oily stain. If the area in question is exposed to pineapple juice, could it not be subject to staining from other food sources?

Just wondering...

Adriana has a good point. It does look like a grease/oil mark - darker.

If it turns out she's right, poultice that dissolves and removes oil is the first order of business.

After that, I'd still polish to unify the gloss and finish removing the soiled part.

An acid landed on the marble. That will always cause an etch whether it was sealed or not. As someone already pointed out, when the etching occurs, it opens the pores for further staining. Get a good quality marble polishing compound and close the pores. MB-11 from mbstone.com is a homeowner friendly product. If that does not work, you need a pro.
