The Best Chemicals for Deep-Cleaning Stone Pavers

Dynamic Stone Tools

Deep-cleaning stone pavers requires chemicals that can effectively remove dirt, stains, and organic growth without damaging the stone’s surface. The best chemicals depend on the type of stone (e.g., granite, limestone, sandstone) and the nature of the stains. Here's a guide to the best chemicals for deep-cleaning stone pavers:


1. General Purpose Cleaners

  • pH-Neutral Stone Cleaner:
    • Ideal for regular and deep cleaning of sensitive stones like marble and limestone.
    • Safe for all stone types, including sealed pavers.
    • Example: StoneTech Revitalizer, Lithofin MN Easy-Care.

2. Alkaline Cleaners

  • Heavy-Duty Degreasers:
    • Great for removing oil, grease, and organic stains.
    • Suitable for granite, sandstone, and other durable stones.
    • Example: Miracle Sealants Heavy-Duty Cleaner, Aqua Mix Heavy-Duty Cleaner.

3. Acid-Based Cleaners

  • Mild Acidic Cleaners (For Durable Stones Only):
    • Effective for removing efflorescence, rust stains, and hard water deposits.
    • Not recommended for acid-sensitive stones like marble or limestone.
    • Example: SureClean 600, Aqua Mix Sulfamic Acid Cleaner.

4. Specialized Stain Removers

  • Poultice Paste:
    • Ideal for deep stains, including oil, rust, and organic materials.
    • Can be applied directly to the stain for targeted cleaning.
    • Example: StoneTech Oil Stain Remover, Tenax Ager Poultice Powder.
  • Rust Removers:
    • Designed specifically for rust stains, safe for most stone types.
    • Example: Faber Rust Remover, Lithofin Rust-EX.

5. Mold and Mildew Removers

  • Biological Cleaners:

    • Remove moss, mold, and algae without harming the stone or surrounding plants.
    • Example: Wet & Forget Outdoor Cleaner, StoneCare Bio-Cleaner.
  • Chlorine Bleach Solutions (Cautiously Used):

    • Effective for killing mold and mildew but should be diluted and rinsed thoroughly to prevent surface damage.
    • Example: A simple mixture of diluted household bleach.

6. Efflorescence Removers

  • Efflorescence-Specific Cleaners:
    • Remove the white, powdery deposits caused by mineral salts.
    • Example: Fila Deterdek Efflorescence Cleaner, Aqua Mix Eff-Ex.

7. Enzymatic Cleaners

  • For Organic Stains:
    • Remove food, beverage, or pet stains with enzyme-based cleaners.
    • Example: StoneTech Mold & Mildew Stain Remover.

8. General Cleaning Solutions

  • Oxygen Bleach:
    • A safe alternative to chlorine bleach for removing organic stains and brightening the stone.
    • Example: OxiClean, EcoGen Oxy Fresh.

Best Practices for Using Chemicals on Stone Pavers

  1. Identify the Stone Type:

    • Ensure the chemical is compatible with the stone to avoid etching or discoloration.
  2. Test in a Small Area:

    • Apply the cleaner to an inconspicuous area to check for adverse reactions.
  3. Dilute as Directed:

    • Follow the manufacturer’s instructions to dilute the cleaner appropriately.
  4. Use Protective Gear:

    • Wear gloves and goggles to protect yourself from splashes.
  5. Rinse Thoroughly:

    • After cleaning, rinse the pavers with clean water to remove any chemical residue.
  6. Seal After Cleaning:

    • Once the pavers are clean and dry, apply a stone sealer to protect them from future stains and wear.
