MB Stone Care Hardscape BSC Outdoor Biological Surface Cleaner

Hardscape BSC is a biological outdoor cleaner that dissolves dirt, grime, mold, mildew and algae from hard exterior surfaces. It is formulated without bleach or peroxides, so it cleans deep into the pores of porous materials without the aggressive chemistry that damages delicate stone, wood and painted finishes. The same bottle works indoors and out on natural stone, brick, concrete, wood, roofing, siding, stucco and fabric. It can be used as a scrub-and-rinse cleaner or left wet as a residual treatment that keeps working on the surface.

Features

  • Biological formula that dissolves dirt, grime, mold, mildew and algae
  • Contains no bleach and no peroxides, so it will not bleach fabrics or attack delicate substrates
  • Penetrates surface pores rather than only lifting soil from the top layer
  • Safe on natural stone, brick masonry, concrete, wood, roofing, vinyl and aluminum siding, stucco and painted surfaces
  • Gentle enough for monuments, headstones and historic masonry that require non-destructive cleaning
  • Biodegradable, non-toxic ingredients with no special handling requirements
  • Two application modes: spray, scrub and rinse, or spray and leave wet for residual action
  • Quart bottle ships with a trigger sprayer

  1. Test Hardscape BSC on a small, inconspicuous area first to confirm compatibility with the surface.
  2. Apply with a soft brush, roller or sprayer, covering the soiled area evenly.
  3. Let the product dwell 10 to 15 minutes on the affected area.
  4. Apply a second wet coat and agitate gently with a soft-bristle brush.
  5. Rinse the treated surface thoroughly with water to remove all residue. Repeat the cycle if heavy growth remains.
  6. On natural stone and masonry, apply evenly, let it sit, then rinse thoroughly.
  7. On painted surfaces, test a small section, apply gently and rinse without scrubbing.
  8. On wood, use a soft brush and rinse carefully to avoid raising the grain.
  9. On fabrics, apply, blot gently and rinse thoroughly.
  10. For residual treatment, spray an even coat on the clean surface and leave it wet instead of rinsing. This discourages regrowth of mold, mildew and algae and makes the next cleaning easier.
  11. Store in a cool, dry place out of direct sunlight and keep the container tightly closed. Gloves are advisable during extended use to avoid skin irritation.

What does Hardscape BSC actually remove?

It is a biological cleaner that dissolves dirt, grime, mold, mildew and algae, reaching into the pores of the surface rather than only lifting soil from the top.

Does it contain bleach?

No. The formula is free of bleach and peroxides, which is why it can be used on delicate stone, wood, fabric and painted surfaces.

Which surfaces can I clean with it?

Monuments and headstones, brick and stone masonry, concrete driveways and walkways, wood fences, decks and furniture, roofing, vinyl, wood and aluminum siding, stucco, painted surfaces and historic buildings.

How long should I let it dwell?

Allow 10 to 15 minutes on the affected area, then apply more product, agitate with a soft brush and rinse.

What is the residual application?

Instead of rinsing, spray a light even coat on the surface and leave it wet. The product keeps working on the surface, discouraging regrowth and reducing how often you need to clean.

Do I need protective equipment?

The product is non-hazardous and needs no special handling, but gloves are recommended if you will be working with it for an extended period.

How should I store it?

Keep it in a cool, dry place away from direct sunlight with the container tightly closed to prevent evaporation and contamination.
