Oil stain in marble

[Brandtly4sincerestone]

I've tried akemi oil and grease remover paste and a ready to use stain remover from regent. Please help! material is white Carrara honed stain is from an oil based putty used by painters

How many applications have you done? Never expect one to be enough

What Ken said. If it only came out a little, that's good. Repeat the process until gone.

With stains, there is never a guarantee, but oil stains usually do come out, it just might take some time.

Regent also carries our stain remover that is for oil and grease stains if the Akemi stuff doesn't work: https://regentstoneproducts.com/item_de ... SCSTAINRMV

Putty stains can be tricky to get out. Maybe try (CAREFULLY) hitting it with a torch and see if you can heat it up and draw some of it out, at least to get it started. I have had success with this a few times

[Ken Lago]

Personally, since it's the plumbers fault I would just replace the top and have him pay for it. It is clearly written on the putty container not to use it on natural stone. Dumb fucker!
Just realized it was a painter not a plumber...ahh well still a dumb fucker.

I agree that poultice often takes more than one application but the other question is did you let the poultice sit covered up until it was dry? Be sure to follow proper procedure and give the poultice time to do what it does. Most people are not patient enough to let it do its thing.

Be sure the oil is all gone before applying any sealer.

I have always had good luck with Comet with bleach and thinner mixed to a paste and covered with plastic.
Leave over night and dry it out with a heat gun or hair dryer the next day

Same reply as in the Restoration Forum.

Heat can also help with oil based stains.

I would heat the stained areas until they are noticeably warm to the touch, then saturate the stained area with Acetone as Dan mentioned. Apply the poultice mix to the stains, and then saturate the poultice with more Acetone and cover with plastic to slow the evaporation. Wait 12-24 hours, then remove the plastic and allow the poultice to dry completely (slowly) before cleaning <== I usually ask the client to perform this step prior to my return. Clean away the poultice and heat again to make sure the area is completely dried.

Repeat until the stain is gone.

It may not be fast, but this WILL work.

Bleach is not always a good idea on marbles. It is an aggressive oxidizing agent and may cause or encourage yellowing and/or rusting in some marbles with iron and/or sulphur present in the stone. Stones like Carrara, Calacutta, some Onyxes or Thassos, for instance.

You might end up exchanging one (fairly easily solved) problem for one that might require extensive remediation.
