How to Clean Concrete & Brick

By Nichole Liandi ; Updated September 21, 2017
Clean brick and concrete on a regular basis to keep them looking like new.

Concrete and brick are both popular materials used in outdoor hardscaping projects like walkways, decks, and patios. Like any materials used in the outdoors, however, it's necessary to clean them on a regular basis to remove surface dirt, mold and mildew. Cleaning brick and concrete doesn't require any complicated tools or special materials--a little elbow grease and some basic household cleaning products will do the trick.

A pressure nozzle makes cleaning concrete or brick go faster.

Attach a pressure nozzle to your garden hose. Adjust the nozzle to create a high-pressure stream. Turn the water on and direct the stream at the brick or concrete surface to rinse loose dirt and debris away.

Mix a solution of bleach and water in a bucket at a ratio of four parts water to one part bleach.

Put on the rubber gloves. Dip your scrub brush into the bucket and scrub the areas you're cleaning with the brush.

Rinse the scrubbed area with a high-pressure stream from the garden hose.

Scrub the surface again if it is not completely clean, working on a small area at a time and rinsing with the garden hose after each pass.
