Cleaning solution: A degreaser for oil spots and a pre-treatment for organic growth; post-treatment slows regrowth.

What to know about cleaning concrete

Plain broom-finish concrete is the surface pressure washing is made for. A rotary surface cleaner gives an even finish without the stripes a wand leaves, and hot water helps with grease and oil.

Avoid: Holding a narrow tip close to the surface, which etches lines into the cream layer of the concrete.

How often: Every year, or every 6 months in shaded, damp spots.

Signs you need efflorescence removal for concrete

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

What causes the dirt and stains

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

Safe steps for homeowners

  • 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

Why more pressure isn’t better

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