The secret to efflorescence removal for brick is using the right method, not the most pressure. In Woonsocket, RI, we match the cleaner and pressure to the surface so it comes out clean without damage. With brick, the right approach is low-pressure wash.
Method and pressure
Cleaning solution: Soft wash for algae and mildew; a masonry-specific cleaner for efflorescence and mortar haze.
Cleaning brick safely
Brick is tough, but the mortar joints are softer than the brick itself, and older soft-fired brick can pit. Organic growth comes off with a soft wash; mineral deposits such as efflorescence need a masonry-safe cleaner instead of more pressure.
Avoid: Zero-degree tips and close-range blasting that erode mortar joints, and strong acids on brick that hasn't been pre-wet.
How often: Every 2-3 years for most homes.

Where the grime comes from
- Water moving through masonry and carrying salts to the surface

- Downspouts and sprinklers soaking the masonry
What you can do yourself

- Fix water sources such as gutters and sprinklers
- Wait out new installations: efflorescence on new pavers often fades on its own
