Marble
To clean: Wipe down the surface using a non-abrasive cloth or sponge and a mild soap and water. Dishwashing detergent can also be used. Avoid vinegar, windex or bleach as these acidic substances will eat into the marble and dull the stone.
Remove stains: Attack stains with the appropriate water- or solvent-based cleaner. Let the cleaner sink in, and then blot it with a microfiber cloth. A more natural method is combining acetone and baking soda to make a thick paste and letting sit on the stain for 24 hours. After the stain has cleared up, clean the marble surface as normal and re-apply sealant, as the acids used for cleaning will cause damage to the sealant.
To maintain: Clean up any spills immediately before they can soak in. Use coasters, cutting boards and placements to keep the surface safe from stains. Any etching in the marble can be fixed by using a marble polishing powder.
Wood
Wood furniture is beautiful, easy to care for, and classic. Quality wood furniture can last generations when properly maintained.
To clean: Wipe away debris with a damp, cotton cloth. You may use mild water on a damp cloth if needed. Always test first on an inconspicuous area. Remove any soap with a clean damp cloth. Wipe dry with a clean cloth.
To protect: Use coasters or other protection to avoid direct contact with wet, cold, or hot items. Use felt pads under any items that will be placed on your furniture and may cause scratches, ex-lamps, coasters, decor. Keep your wood furniture away from any heating source, moisture source, vent, and direct sunlight to prevent fading, discoloration, and warping.
For minor touch-ups: Minor scratches or dents - rub a color-matched marker, shoe polish, or furniture pen over the damaged area to make it less noticeable.
Watermarks - these marks, such as the white ring left under a glass, are caused by excess moisture. To remove the watermark, you will need to remove the moisture. In some cases, the moisture will eventually dissipate on its own. To speed the process, you may use a hairdryer set below 160 degrees F. There are also commercial products that will help remove watermarks.
