Pavers can be used to create sidewalks, walkways, patios and driveways.

Efflorescence occurs in pavers and bricks when water brings salt to the surface of the item, leaving a white, powder-like coating on the paver or brick. Although it appears to be powder-like, it doesn't wipe clean as easily as a powder. However, efflorescence can be cleaned and removed from pavers using the right products. When cleaning pavers or bricks, it's important to use only cleaning solutions safe for those items. Pavers and bricks are porous and will absorb liquids, and chemicals and solutions not safe for pavers or bricks can cause discoloration or damage.


Step 1

Spray the pavers with a garden hose. Set it on a high setting and spray off all dirt and debris, and loosen the efflorescence.

Step 2

Combine warm water with a paver or brick and block cleaner in a bucket. Follow the manufacturer's instructions for the amount of water and cleaner to add.

Step 3

Dip a cleaning brush or medium- to hard-bristled brush into the solution. Brush the pavers clean. Allow the cleaner to dry on the pavers.

Step 4

Use the hose to spray off the pavers and remove soap residue. Allow the pavers to completely air dry.


Step 5

Dampen a cloth with an efflorescence treating product. Rub the cloth on the surface of the pavers so the entire surface is covered in a thin layer of the product. Allow the product to dry. Do not rinse or remove the product.
