Marble Restoration Questions


Q: We used a regular tile and grout cleaner in our marble shower. Why is the shine completely gone, and how can I get it back?

A: Unfortunately, you have used an acid cleaner that etched, or burned, the marble. The only way to restore the shine and color is to call International Stoneworks at (713) 956-8291.

For the proper maintenance of your marble (following the restoration), please browse the Residential Products page for more information on products for sealing and maintaining your stone.


Q: I have a new marble floor, vanities, and shower in my master bathroom. Do I need to seal them?

A: We recommend the following:

For sealing instructions and more information about stone sealers, please refer to our blog,"Smooth Sealing."

Note: The sealer will not protect the marble against acid, ammonia and other inappropriate chemicals.


Q: How do you clean watermarks on marble shower walls?

A: "Watermarks" are actually light etch marks in the marble. Typically you cannot "clean" them. If the marble shower is a few years old, the marble will probably have to be sanded, polished, and resealed by International Stoneworks.

In the meantime, try cleaning with Akemi Crystal Clean and polish with our Stone Essentials™ Countertop Polish to see if it cosmetically hides the watermarks. Countertop Polish contains a liquid wax and some silicone for water-repellency.

Q: I recently had black marble countertops installed in my kitchen, and applied Aqua Mix Stone Enhancer sealant after installation. However, I am already having problems with citrus juice spills "etching" into the stone as well as water marks. I was told by the installer that because the stone is porous, these stains would eventually evaporate out. This does not appear to be happening.

A: Marble contains calcium carbonate, a chemical substance, which reacts to acids. Sealers such as the Aqua Mix or our Seal & Go ® S are meant to protect marble against grease, coffee, tea, milk, etc. BUT NOT acids such as lemon juice, orange juice, vinegar, etc.

I suggest the following procedure to make your life a little less stressful regarding your counter top:

  1. Clean the top every day with a solution of Lavenet or Lavenet Green.
  2. Maintain the polish and protection weekly with Stone Essentials™ Countertop Polish spray:
    • Spray contains a liquid wax, a cleaner and silicone.
  3. Once a year, call us to hone (sand to remove scratches and etch marks), polish and seal the marble.

Remember, nothing will protect the marble against acids, so I recommend you do the best you can to maintain it while using it until it is time to restore it. Many of our stone care products are available in Houston at certain retail locations.


Q: I've had hurricane damage to my marble floors. My once beautiful marble floor looks dull and discolored. What can I do to get my marble floor back?

A: The removal of shine and the discoloration indicates to me that you have water damage. If the water came from the surface (from flooding for example), the discoloration and lack of shine is most likely from debris.

I would recommend you damp mop the marble floor with a neutral cleaner such as Lavenet or Lavenet Green and then dry as best as you can with floor fans and dehumidifiers. Then call International Stoneworks at (713) 956-8291 to professionally clean, resurface, and bring back the shine with our grinding system. We can also use the poultice method to remove deeper stains. However, in certain cases, some stains may be too deep to remove.

If the water came from underneath the marble, that is a more damaging problem as it has penetrated throughout the stone from the bottom up. In this case, you need to look into replacing your marble floor.

For more information on how to prevent future damage in the case of a storm, please refer to our blog, "Simple Ways to Protect Your Stone During Hurricane Season."


Q: I have marks on my marble floor after my dog had an accident on the marble. The spots are all over the floor. Do you have a product to clean these spots?


Q: I have a ten year old marble floor that has lost its shine. I thought stones would last forever.

A: Stone actually does last for a very long time. However, the shine on the surface of the stone does not. A 10-year-old marble floor needs to be professionally restored. Call International Stoneworks if you are in or around the Houston area. If this service is not available in your area, you can try:
