Caring for Your Stonework
NATURAL STONE CARE & CLEANING
TYPES OF STAINS & FIRST STEP CLEANING ACTIONS
(grease, tar, cooking oil, milk, cosmetics)
An oil-based stain will darken and must be chemically dissolved so the source of the stain can be flushed or rinsed away. Clean gently with a stone cleaner or use bleach, ammonia, mineral spirits or acetone. If not making progress, check with us for specific recommendations.
(coffee, tea, fruit, citrus, red wine, tobacco, paper, food, urine, leaves, bark, bird droppings)
Organic stains may create a pinkish-brown color and more than likely, will disappear after the source of stain has been removed. Clean gently with a stone cleaner or check with us for specific recommendations.
(iron, rust, copper, bronze)
Iron or rust stains are orange to brown in color and follow the shape of the staining object such as nails, bolts, screws, cans, flower pots, or metal furniture. Copper and bronze stains appear as green or muddy-brown color and result from the action of the moisture. Call us for a poultice or a cleaner recommendation.
