Will Metal Brush Damage Deck When Cleaning?

Do Metal Brush Damage Wood Decks?

Yes, the metal brush can damage your deck when cleaning. But wait… At first, you might be safe using a wire brush on your deck and it’s all about how much pressure you use and how often you’re using it.

If you’re using a lot of pressure, or if you’re using it too often, then yes, it will damage your deck. You should always start with a light touch and gradually increase the pressure as needed; if you start off too strong, there’s a chance that you’ll cause more damage than good.

And if you’re doing this regularly (like every time you wash your car), then that’s even worse because now all of those scratches from before have been made deeper by repeated use. So if you do plan on using a metal brush to wash your deck, make sure it’s only every once in a while!

Can you Use A Wire Brush to Clean the Decking?

It’s possible to use a wire brush to clean your deck, but you’ll need to take some precautions.

If they have coated the deck with a finish such as paint or stain, you can’t use a wire brush. The bristles could damage the finish and leave scratches on the wood. The same is true if you have cedar decking that hasn’t been sealed since they installed it.

If your deck is bare wood or if it’s been treated with sealer, you can use a wire brush on it, with little to no pressure. Make sure that the bristles are soft enough not to scratch the wood. If they’re too stiff, they may cause gouges on the surface of your decking.

A wire brush will remove dirt and debris from between boards on your deck, but it won’t clean off stains or mildew from them. If you want to remove those kinds of stains from your decking, consider using bleach or another bleaching agent instead of water alone for cleaning.

What is The Best Thing to Clean Decking With?

The best thing to clean decking with depends on what type of decking you have. For example, if you have cedar, use a special cleaner that is designed for cedar, but if it is pressure-treated wood, then you need to use a different product.

If you want to clean your deck without using harsh chemicals, then try using natural products such as vinegar or lemon juice and water. You can also use baking soda and water or even hydrogen peroxide.

However, if you have mildew or mold on your decking, then it is going to take more than just vinegar and water to remove it. This is where bleach comes in handy as it kills off mildew and mold spores and kills bacteria, which can create odors from the decay of dead plants or animals.

A Stiff, or Softer Bristle Brush on Wood Surfaces

A stiff bristle brush on wood surfaces will speed up the cleaning process, but it’s still better to use a softer bristle brush.

If you’re cleaning your deck with a metal brush, you are going to damage your deck soon. There are some other options available to use. To speed up cleaning your deck, use a stiff bristle brush on wood surfaces.

We did, will recommend using the “17.7 inches Wide 61.8 inches Push Stiff Outdoor Rough Surface Floor Scrub Brush,” from the LandHope Store, for cleaning your deck.

For example, if you have a large deck and want to do it quickly without damaging the wood, go for a stiff bristle brush. But if you’re cleaning a small section or two of your decking in between coats of stain or paint (and don’t mind doing it by hand), then using a soft bristle brush is fine and will not damage your wood as long as you’re careful when using it.

Are Power, or Pressure Washer Perfect for the Deck

The power or pressure washer is only washing away dirt and leaving the wood clean, so you don’t have to worry about damaging anything.

They designed a pressure washer to clean away dirt, grime, and soil from a surface. They used high-pressure water that can strip paint in seconds, so it’s no surprise that you might think a power washer would damage your deck. But there are two important things to keep in mind:

  • The power or pressure washer is only washing away dirt and leaving the wood clean, so you don’t have to worry about damaging your deck areas.
  • A deck needs upkeep just like every other surface under our feet daily; it’s just not as obvious as some other areas of your home because of its location outside (and far away from where you’re showering!).


  • If you are using a power washer along with detergent, then pay attention to how much you are using.
  • Use a soft bristle brush or broom.
  • Use the right detergent.
  • Use the right pressure and nozzle to avoid damage to your deck or siding.
  • Don’t use too much detergent, as this can cause streaking or etching on painted surfaces.
  • Make sure you’re using a power washer with the correct nozzle and hose size for the job you are doing (a smaller nozzle will remove more dirt from delicate areas).

Using Power Washers can Help Clean your Wooden Surfaces, but Don’t Overdo It.

With a power washer, you can clean your decking in a matter of minutes. However, the power of these machines may make it tempting to use them too frequently or for more serious cleaning jobs than is necessary.

It’s best to limit the use of power washers to only once or twice per year and stick to using them on surfaces that have not been sealed. If this is not possible, consider using another method, such as manual scrubbing with a deck brush (softer bristle brush).

Power washers should never be used with metal brushes because they can cause damage to your decking over time by breaking down its finish and exposing bare wood fibers beneath it.


You shouldn’t use metal brushes on your deck because they’ll damage it. Instead, you should use the correct cleaning method that will result in a durable, easy-to-maintain deck.
