How we clean it

Masonry cleaner and low-pressure rinseCleaning method

Signs you need efflorescence removal

  • White powder or crust on brick, block or pavers
  • Haze that comes back after rain
  • White lines along mortar joints

Where the grime comes from

  • Water moving through masonry and carrying salts to the surface
  • New pavers and concrete still curing
  • Downspouts and sprinklers soaking the masonry

What you can do yourself

  • Brush dry efflorescence off with a stiff brush before wetting it
  • Fix water sources such as gutters and sprinklers
  • Wait out new installations: efflorescence on new pavers often fades on its own

What can go wrong with DIY pressure washing

  • Washing with plain water, which can dissolve salts and redeposit them
  • Strong acids that burn masonry
  • Sealing over efflorescence, which traps it

Do you use high pressure for efflorescence removal?

Efflorescence Removal is done with masonry cleaner and low-pressure rinse. Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.

Is efflorescence removal safe for my plants and pets?

We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.

How often should I schedule efflorescence removal?

As needed; it can return until the moisture source is fixed. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.

What if it rains on the day?

Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
