Why is there white stuff on my bricks?

Efflorescence is a white crystalline or powdery, often fluffy/fuzzy deposit on the surface of masonry materials like concrete, brick, clay tile, etc. It’s caused by water seeping through masonry or cement based material. Brick is a sponge – not a barrier – against moisture.

How do you get rid of white leaching on brick?

Fill a regular spray bottle with white distilled vinegar if efflorescence lingers. Disperse the vinegar generously onto the bricks, thoroughly drenching the efflorescence. Let the efflorescence absorb the vinegar for five minutes.

Vinegar and water solution—Efflorescence can be removed by using a dilute solution of household white vinegar and water. A vinegar and water solution is relatively inexpensive, non-toxic, and easy to obtain, mix and apply. Dilution ratio is 20–50% vinegar in water by volume.

How long does efflorescence last for?

Efflorescence can come and go over a period of a few weeks but can take many months in some cases. Local conditions and climate play a part; damp shaded areas tend to be more prone to efflorescence than drier sunnier areas and efflorescence can be more pronounced during springtime following a wet winter.

Is efflorescence harmful to breathe?

Unlike mold, efflorescence isn’t normally harmful to human health, but it can cause mild irritation if inhaled or if it comes in contact with the eyes. Even so, efflorescence doesn’t usually float freely in the air as dust. Pressurized water can dissolve efflorescence and clean away the mineral deposits.

On the other hand, white mold penetrates the surface of porous materials like wood or drywall and can ruin them.

What is white stain on brick?

White marks on bricks — and other masonry items — are typically mistaken for mould, soil leaching or water stains. However, efflorescence is normally the cause of the white marks. Efflorescence occurs when dissolved salt runs down the brick, leaving an unsightly mark.
