What to Look For (Buying Guide)

Even though we’ve narrowed it down to the top 10, it’s still important to consider what’s important to you to make sure you choose the best one for your deck.

Deck Material

The absolute most important thing you need to consider is your deck’s material. Decks come in a range of materials, and not every cleaner can handle each type. Is your deck made of wood, vinyl, composite, concrete, or something else?

We’ll let you know what materials each cleaner can clean, so you’re not left in the dark.

Purpose

Next, consider what the purpose of the deck cleaner is. Is it just general cleaning, or does it go the extra mile? If you have mold, mildew, algae, or other stains on your deck, make sure to choose a cleaner that can get rid of these.

Eco-friendly

Lots of people are going green with their choice of cleaners. Especially when it comes to outside cleaners as you may want something that will be kind to the surrounding environment.

Always check the ingredients of the deck cleaner to see how natural it is. You should also check if it’s plant and pet safe.

Not many deck cleaners have gone green or natural yet, but we do have a few great recommendations if that’s important to you.

Pressure Washer Compatibility

If you have a pressure washer, plenty of deck cleaner options will work with your beloved power tool. If you don’t have a pressure washer, make sure you’re choosing something that can be used without a pressure washer.

Versatility

You might want something that can clean more than just a deck. There are many options on our list that can be used on a range of materials. In fact, some work for both indoor and outdoor materials.

On the other hand, you may want a cleaner that can do more than just clean. For example, some deck cleaners can also seal the deck, protecting the surface from dust, dirt, and other stains. They may also act as a water repellant to diminish mold, mildew, and algae growth.

Value for Money

When it comes to household products, nobody wants to waste a penny. To get the most bang for your buck with deck cleaners, always check the cost per fluid ounce.

You should also consider whether the cleaner is premixed or concentrated. Generally, concentrated cleaners go further since you can dilute a little bit of the solution with water.

Last but not least, check out if the manufacturer discloses a coverage volume. This will give you a rough idea of how far the deck cleaner solution can go so you know if you’re getting your money’s worth.


FAQs About Deck Cleaning

Can You Use Bleach to Clean Decking?

Yes, bleach is suitable for deck cleaning, and that’s why it’s used in many of the most popular products. However, it’s a good idea for the bleach to be diluted properly and effectively. So we recommend choosing one of these bleach-based cleaners rather than straight bleach.

Will Vinegar Clean Wood Deck?

Yes — mix a 1:1 solution of water and vinegar, and it will work well to clean your deck. It can also remove mold and mildew stains.

Should I Pressure Wash My Deck?

A pressure washer is one of the most effective ways to clean your deck. The power of water alone can often be enough to spruce up the deck and remove stubborn stains.

Top Tip

Try pressure washing your deck without a cleaning solution first. You may find you don’t actually need the additional power of a cleaner.

How Do I Clean My Deck Without Chemicals?

The most effective way is purely with a pressure washer. This is how we clean our deck, and it works wonders. You can also use eco-friendly and non-toxic cleaners, such as the Simple Green Oxy Solve Deck Cleaner. White vinegar is also suitable.

How Do I Make My Own Wood Deck Cleaner?

There are many recipes out there for a DIY deck cleaner. Here is one that’s easy to make and contains no harsh chemicals:

  • Two gallons of hot water.
  • Two cups of powdered oxygen bleach.
  • ¼ cup of dish soap.

Mix these and apply them to your deck with a brush.
