Stone Restore A+

Stone Restore A+ (Alkaline Technology) removes stubborn environmental staining as well as oil and grease stains from most types of stone.


This product contains a combination of environmentally friendly surfactants, builders, solvents and acids, which are developed for cleaning stone surfaces of all types. This product removes a thin layer of substrate at a molecular level in order to remove stains caused by rust, minerals, corroding metals and more.

  • Water-based
  • Cuts through stubborn oil and grease stains
  • Removes black environmental staining on multiple surfaces
  • Effectively cleans painted surfaces
  • Low odor
  • Cost-effective
  • Fast-acting


This product is primarily used for horizontal surfaces as it is incompatible with glass and may cause stains if allowed to dry on the surface. 


600 to 3,000 feet per 5 gallon pail depending on dilution rate.


This product is designed for use on most types of stone. Special precautions are required when using this product to clean limestone, marble or travertine.


We recommend the use of one of Presto's stone protective treatments to protect the newly restored surface for years:
  • Protective gear 
  •  Running water 
  • Chemical sprayer 
  • Pressure washer (optional) 
  • Stone brush (optional)

Stone Restore A+ should be used at a dilution rate of at least 3 to 1. For light stains, dilute 1 to 9 with water. For horizontal concrete with stubborn oil stains, start by using a 3 to 1 mix, then dilute as needed.

Protect unintended surfaces from contact, including traffic and pedestrian areas below the project, electric tools, wood, furniture, fixtures and plants. Always test in a small, inconspicuous area prior to use.


Wet the surface prior to application. Have running water available to keep the surface damp. Apply an even coat of cleaner using a low-pressure (40 psi max.), chemical resistant sprayer. Keep area moistened with Stone Restore A+ to loosen soil. Immediately rinse any unintended surfaces, such as glass or frames. 

For deep stains, allow the cleaner to penetrate into the substrate for 10-20 minutes, but never allow surface to dry. 

After product has saturated the surface, rinse using a pressure washer and a white, 40-degree tip or a green, 25-degree tip. Keep the tip as far away from the surface as possible. If a pressure washer is not available, use a brush to help loosen stubborn soils. Always rinse area thoroughly to ensure no product is left behind.

Multiple applications may be required for heavily soiled, porous or absorbent surfaces. Apply immediately after initial application. Follow the same instructions for each application. For best results, rinse with heated, deionized water. 

Situations including various stone types or different natured stains may require multiple products. Presto’s stone cleaning line includes:
  • Stone Restore® HD For difficult to remove mineral stains caused by efflorescence, rusting, red clay, iron and more 
  • Stone Restore® NC For general cleaning of sensitive stone surfaces that require a neutral cleaner 
  • Stone Restore® CT A multi-purpose stone cleaner that removes a variety of stains from all types of stone materials 

Take special precautions when using any alkaline cleaner. Stone Restore A+ may cause discoloration of stone or affect adhesion of water repellants if used incorrectly. Never let this product dry on surface. Product may cause etching on glass surfaces.
