Inspect Stucco Before You Clean

This may be one of the most important stucco maintenance tips – Cleaning damaged stucco can result in even more damage. Before you do any cleaning, check your stucco for chops, cracks or any other flaws. Any damage you discover must be repaired first, otherwise, moisture can seep into and stain or discolor the stucco. While you may be able to repair minor damage such as hairline cracks or small chips yourself, you should definitely hire an experienced professional for all other repairs.



Minor chips and cracks should be sealed with color matched exterior acrylic caulk. It may be difficult to match the color exactly, but you will be able to get a close enough match that minor repairs won’t stand out. To duplicate the texture of your stucco, you can press a gritty substance like sand into the caulk while it is still wet. Once the repairs are complete, allow the caulk to dry for at least a week before attempting to clean the stucco.

The usual culprits are mildew and algae, both due to excess moisture. Mildew will be black and looks similar to dirt and algae will be green. With small areas of staining, you should be able to clean them yourself.

Of all the stucco maintenance tips, this one will make the job more manageable. First, saturate an area with water. This can be done with a hose or a power washer. With a power washer, use the low-pressure tip and keep it at least 24 inches from the wall.

Apply the cleaning solution with a single pump sprayer. Start at the bottom of the section, work up to the top and let the solution sit for 5 to 10 minutes. Then scrub the wall with a brush and finally, rinse it thoroughly from top to bottom with the hose or power washer to remove all of the debris and cleaning solution.

When cleaning stucco, there are a couple of different cleaning solutions that can be used. The first is a mixture of concentrated exterior cleaner and bleach. Concentrated cleaners can be found at home improvement stores. The cleaner should be labeled “professional strength concentrate” and include ingredients like acetic acid and sodium o-phenylphenate. These cleaners are typically activated by with bleach and hot water. The correct proportions of each will be listed on the package and safety goggles and gloves should always be worn when applying this cleaning solution.
