However, The Marble Man stone restorers can remove all traces of stains and other damages due to negligence.

Natural Stone Stain Removal Guidelines
STAIN DOs
1. Identify the stain if possible as this will determine the treatment. It could be water based (some paints), alcohol based (wine, spirits, marker pen), oil based (grease, cooking oil), metal based (rust), organic (coffee, tea, milk, food, bird droppings, make-up, tobacco), or biological (mould, mildew, lichen).
2. Consult your stone care professional and tell them as much as you can about the stain. If you would like us to inspect your stone and advise on proper stone repair or restoration, call our office on 1300 627 626 and an experienced team member will visit at a time convenient to you and provide a no obligation, free quote. Or else, you may email us to book your onsite evaluation. Contacting The Marble Man is the safest way to avoid damaging your stone and to ensure that the stain is completely removed.
STAIN DONT’S
1. Avoid using chemicals unless recommended, as these may damage the stone or set the stain if not appropriate.
2. Avoid using heat especially on albumin based stains (containing protein) such as blood or milk as it may cook and set the stain.
What The Marble Man can do to remove stains on stone surfaces
The most effective and common method used by our stone care professionals to remove a stain from natural stone is to apply a poultice. A poultice is made with a powder and a special treatment product, which is determined by the type of stain.
The powder is mixed with the treatment product to form a paste, which is then thickly applied to only the affected area. It is covered with plastic wrap, the edges sealed and small holes made to allow the powder to dry. As the mixture dries it draws the stain from the stone and absorbs it.
After removing the poultice the area is washed with pure water and polished with a soft cloth and a cleaning product suited to the stone.
The poultice method is effective for removing common stains such as coffee, iodine, blood, chewing gum, ink, paint, rust, acidic liquids, efflorescence (a white substance which can develop on some stone), graffiti, water, mould, mildew, lichen, dull and coloured spots.
At The Marble Man in Australia, our team members receive hands on, practical training on stone care (stain removal, stone polishing, natural stone repair, restoration etc.) processes and are kept up to date with the latest stone restoration techniques and technology.
