StoneTech Clean FAQs

  1. How do I keep my stone clean?
    We recommend using a cleaner specially formulated for natural stone. General purpose cleaning products can damage natural stone or the sealer applied, so don’t just pick anything off of the shelf at the grocery store. Improperly formulated cleaners or those with acids (such as porcelain or tile cleaners) may etch the surface of the stone. Make sure that you select a cleaner specially formulated for natural stone care.
  2. How can I clean mildew off of my grout in the shower?
    Is there preventative care?We do have a cleaner called StoneTech® Professional KlenzAll™ Cleaner that will help clean your grout and help remove some of the mildew.If there is any remaining mildew growth you can get a 50/50 solution of water and household bleach and clean those areas. Make sure that you rinse the area with clean water thoroughly before continuing to seal. Once this has been done, you need to wait about an hour and seal with our water-based sealer, Heavy Duty Sealer.
  3. How do I clean my just-installed, sealed stone countertops?
    Our suggestion for your ongoing care would be to use our Revitalizer® Cleaner and Protector. Not only is this an excellent cleaner for removing everyday soils and spills, but every time that you clean you're reinforcing the protection of the intial sealing.
  4. How do I remove the epoxy grout haze all over my stone tiles?
    Since we know it is an epoxy gout haze, we would suggest using our Heavy Duty Coating Stripper. Apply the stripper following label directions. After stripping, make sure you maintain daily with Revitalizer® Cleaner and Protector or Stone & Tile Cleaner.
  5. I put something down on my polished white marble table and it left a white ring mark on it. How can I clean this spot?
    This kind of discoloration and ring mark that you are noticing are likely not stains but actual etch marks. Etch marks occur on polished marble and other stones of this nature due to acids or other chemicals reacting with the minerals in the stone. This causes the stone to feel rough and look a little discolored, usually lighter. In order to remove these there would have to be a refinishing process done to restore its original, polished look. Fortunately, we do make several products that will help refinish the stone. We would recommend visiting Duponts care instruction section of our website.
  6. There's a hazy, grout-like residue smeared all over my just-installed ceramic tile floors. Can this be fixed?
    The haziness that your see is probably grout smear from the installation process. This can be safely removed using our Restore™ Acidic Cleaner for Ceramic Tile and Grout. Make sure you protect all walls, baseboards, carpeted areas, plants, foliage and metals. Restore™ may damage stainless steel and other surfaces. Sweep or dust mop loose dirt and debris off of the floor. Prepare a solution of 1 part of Restore™ mixed with 4 parts of warm or hot water. Liberally apply over your floor using a sponge or mop. Agitate well using a stiff nylon bristle scrub brush or stiff bristle push broom. Rinse well with clean water and mop, sponge or wet vacuum to remove the remaining solution. Repeat the rinsing and wet vacuum process to insure that all dirt, soil and cleaner residue have been removed. Thoroughly rinse all metal surfaces. We would strongly recommend sealing the floor once you’ve remove the grout haze to protect it from staining and soiling. Use our Grout Sealer for protection against oil- and water-based stains.
