However, before you begin care and maintenance, you should be aware of what you are getting yourself into. If you want to understand how to clean your deck, you should first consider the advantages and disadvantages of wood and composite lumber deck. If you clean your deck on a regular basis, you should be aware of any additional maintenance activities that may be required from time to time.

Composite Decking and Wood Decking

If you prefer natural wood, you should clean your wood deck once a year. You can buy a deck cleaning solution from the hardware store or make your own by combining various home materials. These cleaning products are highly successful at removing mould, algae, grease, and dirt.

In addition to cleaning, you should paint or seal your natural deck on a regular basis. This repair preserves the deck’s beauty while also protecting it from weather deterioration. Natural wood decking can fracture, thus loose boards may need to be sanded or replaced on a regular basis.

Overall, a composite lumber deck is easier to maintain. Because they do not crack, you will not need to stain, paint, or seal them as frequently. To keep your composite decking looking great, simply clean it on a regular basis.

All you need to clean your deck is a stiff-bristle brush and a deck-cleaning solution. A bucket, a cleaner, an outdoor hose with a nozzle or a power washer, and an extension pole-mounted brush are required. Scrubbing your hands and knees can be avoided by using an extension pole brush.

In addition, there are several homemade cleaning methods you may use to safely clean your deck. They are compatible with both natural wood decking and composite decking. You can purchase these products at your local hardware or food shop.

Depending on the homemade combination and whether your deck is composed of wood or composite decking. The things listed below can be used in various numbers and combinations to help keep your deck in good condition. Among them are:

  2. Clean your deck safely with warm water and ammonia-free liquid detergent. A gallon of water, two tablespoons of dishwashing liquid, a pint of alcohol, and a quart of oxygen bleach combined will do the job. Use the combined detergent to clean the deck, then rinse with water.
  3. Oxygen bleach or powdered oxygen laundry cleanser is safe to use on wood decks and effectively removes mould and spores. When cleaning your deck, use only oxygen bleach and not chlorine bleach. Chlorine bleach can cause harm to the deck’s wood surface.
  4. Adding vinegar to water is safe for both wooden and composite decking planks. Combine ¼ cup baking soda with ½ cup white or apple cider vinegar.

How to Clean Wood Decks?

Natural wood decks look fantastic when kept in good shape. A solid wood deck can get highly worn over time if it is not properly cared for and cleaned regularly. Summer fun and picnics, as well as winter cold and frost, can cause significant damage to them.

Follow these methods to properly clean your wooden deck: 

  1. Rinse the deck first. First, sprinkle water onto the wood deck to begin softening the dry cellulose. This “pre-rinse” also makes it easier for the cleaner to reach all areas of the deck.
  2. Mix the cleaner you choose. Follow the instructions on the bottle and combine the cleanser with water in a 5-gallon bucket. Or you can make your own cleaning goods.
  3. Scrub the deck. Then, using a stiff-bristled brush, scrub the deck along the grain to remove dirt, mould, mildew, and other debris. If the deck is vast, use additional cleaning solutions and keep them separate. The concentration of the cleaning solution should be consistent throughout the job.
  4. Rinse it off. Finally, rinse the deck with a yard hose or pressure washer. If possible, wash the wood deck when the weather is pleasant. If possible, let the wood deck dry for 24 to 48 hours before staining and sealing. 

How to Clean Composite Decks

The best technique to clean a wood deck differs from that of composite lumber deck. Performing the proper maintenance and cleaning on your decking can keep it looking great and useful for a long time.

The first step in keeping composite decking in good condition is to avoid using household chemicals that are beneficial to genuine wood decking. These chemicals can make a wood deck appear new. However, some of these more potent compounds can degrade the composite decking material. Nobody wants to damage their deck rather than improve it.

You may buy composite decking cleansers, but cleaning composite decking is a quick and easy process. You can easily keep your deck clean as new using items you may produce at home.

A mixture of soap, water, vinegar, and baking soda (for mould and mildew) creates an environmentally friendly composite decking cleaning. Use a gentle pressure washer (with a maximum pressure of 3100 psi) or a soft-bristled brush to remove dirt, debris, and grime. To guarantee that your composite decking lasts as long as possible, clean it once every six months.

  1. Spray the deck first. Spray the composite decking first with a hose and water to remove any surface dirt or waste.
  2. Spray with soapy water water and scrub. Then spray soapy water on each deck board and gently scrub each composite deck with a soft bristle brush.
  3. Rinse clean. Once the deck’s surface has been washed with soapy water, thoroughly rinse with clean water. This is significant because allowing dirty water to dry after washing may result in a film on the surface of the composite deck.

Removing Mold from Composite Decks

To remove mould from composite decking, use a vinegar and water solution.

  1. Rinse first. Using a hose or power washer, remove as much mould from the deck’s surface as possible.
  2. Mix the vinegar solution. Then, combine two parts vinegar and one part of water in a bucket. Pour the solution over the top of the mould.
  3. Add baking soda. After pouring the vinegar solution, sprinkle baking soda over the mould. Soak the area with the compound for 20 minutes. Brush off the mould with a soft-bristled brush.
  4. Rinse thoroughly. Finally, thoroughly rinse the area, ensuring that no film remains.

To Summarize

This is all there is to cleaning wood and composite decks! To maintain your deck clean and in good shape, simply use a little soapy water, light pressure, and the cleaning recommendations listed above. Then you’ll be able to enjoy the wonderful outdoors with your family.
