Do Some Retaining Walls Get Dirtier More Easily?

When it comes to retaining walls, there are many different types of stones that can be used, each with different pros, cons, and costs. Some stones are more porous than others, and these stones tend to get growths more easily. This is because the pores in the stone allow for moisture and other debris to get trapped, which can then lead to the growth of algae, moss, and other unsightly growths.

While it is possible to clean these types of stones, it is often more difficult than cleaning other types of retaining walls. If you have a stone that is prone to getting dirty, it is important to take extra care when cleaning it so that you do not damage the stone or the wall itself.

How To Clean Retaining Wall Blocks

1. Remove any debris

It’s important to remove any debris from the wall before you start cleaning it. This will help make the job much easier and ensure that you don’t miss any spots.

2. Use a hose to wet the wall

Once you’ve removed all of the debris, you can use an ordinary garden hose to wet the entire wall down. This will help loosen any dirt or grime that’s built up on the surface. You can use a garden hose for this step or a pressure washer (we’ll cover this cleaning process later in this article.)

3. Apply A Cleaner

There are a variety of cleaners you can use to clean your retaining wall blocks. A pressure washer with a detergent attachment is often the best option, but you can also use a garden hose with a spray nozzle or even a bucket of soapy water.

4. Scrub The Stone

Once you’ve applied the cleaner, use a brush to scrub the stone. A stiff bristled brush will work best for this step. You’ll need to put some elbow grease into it, but eventually, all of the dirt and grime will come off.

5. Rinse The Wall

After you’ve scrubbed the wall, use a hose to rinse it off. Make sure to get all of the cleanser off of the wall so it doesn’t leave any streaks.

6. Let It Dry

Once you’ve rinsed the retaining wall blocks, let them dry completely. This usually takes a few hours, but it can take longer if it’s a cloudy day or if the wall is in the shade.

7. Check The Wall
