An etch is a dulling mark on stone that appears as a stain. An etch is a chemical reaction between the calcium in the stone and any liquid that has an acidic PH
Liquids such as beverages, food items and cosmetic items with an acidic PH can etch the finish of your stone.
The acidic nature of any item will react to the calcium in your stone leaving a dull mark that cannot be removed with cleaning.
Scratches can occur on softer stones such as marble, limestone, travertine, onyx and soapstone.
Scratches ruin the finish of your stone and cannot be removed with cleaning.
Our Slate Cleaning & Polishing Process
Our natural stone cleaning systems are performed to IICRC standards for S210 stone restoration. We use the most cutting-edge technology to deliver the ABSOLUTE BEST CLEAN. Our standard natural stone cleaning process removes any topical soil. Any staining or damage not removed by our standard natural stone cleaning process will require either a “partial restoration” or a “full restoration”.




- Pre-Treatment: spray application of our alkaline trimix chemical with the purpose of breaking the surface tension of the soil, penetrating the grout in order to defloculate imbedded soil. It then breaks down soil and suspends it in the water molecule/cleaning detergent for easy removal.
- Agitation: Manual or Mechanical – Aids the Pre-Treatment to saturate, and helps further loosen soil.
- Extract: done via truck mount or portable machine vacuums off suspended soil in water molecules
- Rinse: Triple Steam rinse flushes out any dirt remaining in the tile & grout ensuring full removal.
- Emulsify: a chemical rinse that is the 2nd rinse step synergistically reacts with the pre-treatment to attract all chemical and soil to the surface
- Neutralize: a chemical rinse that is the 3rd step in the rinse step that flushes all residue and solutions out, neutralizes them, and brings the tile & grout PH back to balance PH7 to prevent re-soiling.
- Speed dry: expedite drying to eliminate/avoid efflorescence
- Dry Buff: Removes any remaining residue, also aids to expedite drying
- Seal: Application of appropriate deep impregnating/penetrating sealer. (sealers may vary depending on the type of stone)
- Final Buff: Ensures full penetration of sealer, removes any excess sealer residue.
