What to know about cleaning stone & stone veneer

Natural stone and manufactured stone veneer vary a lot. Manufactured veneer is cast concrete with a colored surface that high pressure can wear off, and limestone and sandstone are softer than granite.

Avoid: High pressure on manufactured veneer, and acidic cleaners on limestone, marble and other calcium-based stone.

How often: Every 2-3 years.

Is it time for soft washing for stone & stone veneer?

  • Green, black or gray film on siding, especially on the north side
  • Black streaks running down the roof
  • Moss or lichen on shingles or tile
  • A musty smell around shaded walls
  • Pressure washing would damage the surface

Why it gets dirty

  • Algae, mold and mildew that grow in shade and humidity
  • Roof algae that feeds on the limestone filler in shingles
  • Pollen and dust that give growth something to hold on to
  • Sprinklers and gutters that keep walls damp

What you can do yourself

  • Trim back branches and shrubs that touch the house so walls can dry
  • Keep gutters clear so water doesn't overflow down the siding
  • Spot-clean small areas with a soft brush and mild detergent
  • Aim sprinklers away from the house

Common mistakes to avoid

  • Using too strong a mix, which can burn plants and fade surfaces
  • Using too weak a mix, which leaves growth alive and it returns quickly
  • Climbing ladders with a spray wand and chemicals
  • Mistaking soft washing for 'pressure washing on low'

Soft Washing for Stone & Stone Veneer in California

In California, stucco and siding mostly collect dust, cobwebs and sprinkler spots, while shaded walls can grow mildew after winter rains. A soft wash handles both without etching stucco.

Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.

Much of California has hard water. Sprinklers and misters leave white mineral spots on walls, windows, fences and pool tile, and those spots need a mineral-safe cleaner, not more pressure.

Some cities in California limit outdoor water use, including washing hard surfaces with a hose, especially during drought declarations. Pressure washers use far less water than an open garden hose, but rules vary, so it's worth checking your city's current restrictions. Wash water should also be kept out of storm drains.
