How to Remove Adhesive from Marble: Four Methods
Adhesive stains on marble tops usually come from adhesive tape. Over time it will leave a sticky residue that has a dark appearance. These stains can also collect dirt which can further make its texture uneven; they cannot be removed completely by manually scrapping them off with your hands. Learning how to remove adhesive from marble is relatively easy, however, and can be performed using a few readily available tools and materials.
1. Remove Using Soap and Warm Water
Sometimes the simplest method can be the best; a sponge dipped in soapy warm water can be all you need. First, mix warm water with soap until you see suds build up. Next, soak a sponge or cloth with the solution, and rub the adhesive stain until it softens. Continue rubbing the material until the mark comes off. Rinse the affected area with clean water, and then wipe away any residue with a clean, dry cloth.
2. Remove Using Cornstarch, Talcum Powder, or Vegetable Oil
Sprinkle cornstarch or talcum powder on the adhesive; then, rub with a dry cloth until the mark comes off. If the stain persists, try using vegetable oil. Let it sit on the affected area for a few minutes until the mark softens, and then scrape it off using a metal spatula or the dull edge of a knife. You will still need to clean the affected area afterward using a mixture of dish detergent and water.
3. Remove Using Rubbing Alcohol or Mineral Spirits
Soak a cotton ball in rubbing alcohol or mineral spirits, and rub the adhesive mark until it's removed. Wash the spot with a mixture of water and soap to remove any chemical residue before you pat it dry with a cloth or towel.
4. Remove Using WD-40
Another product that is effective in removing stubborn adhesive stains is WD-40. Spray the mark with the lubricant, and then gently scrape off the stain using a dry cloth. Once again, you'll need to wash away the remains with soapy water, rinse the spot, and wipe it dry.
Solutions to Avoid
Do not use abrasive products or acidic cleaners as this can damage your marble. If you're unsure about the contents of a cleaner you want to use, test it by putting a few drops first on a small area to see how the marble will react. Also, some cleaners contain solvents that are flammable, so care should be taken when using such products. Never use them in closed areas or anywhere with an open flame as they could easily catch fire.
Marble is beautiful, but expensive, so don't ruin your investment; remember to be patient and follow the proper techniques.
