Decks need to be cleaned from time to time, and the process doesn't need to be as difficult as you may think. Pressure washers are commonly used for deck-cleaning, but come with the potential for damaging the surface of the deck if used incorrectly. This is because some woods are relatively soft and can splinter under the high PSI put out by many pressure washers. Chemicals are another option and can be effective, as long as the right ones are chosen. Here are some tips to make cleaning your deck less difficult and to keep you from damaging it:
Sweep Thoroughly
Failing to get rid of all the dust and sand on the surface of your deck could result in a muddy, grimy mess once you start to power wash or apply cleaners.
Inspect for Rot
If you find that some boards are damaged beyond repair, this is the best time to replace them. You should also check to see if your deck needs to be sealed in order to prevent rot further down the road. If a drop of water dripped onto the surface soaks into the wood, you should consider resealing it after cleaning.
Use a Pressure Washer on Your Deck
To avoid damaging softer woods used for deck construction, you should opt to use a PSI no greater than 1200. Additionally, you will want to use the sprayer fan for the best effect. The spray arc should be between 25 and 40 degrees.
Choose the Right Deck Cleaner
Your options will include chlorine bleach, oxygen bleach and oxalic acid. These three chemicals are ingredients in most of the commercial deck cleaners available on the market. One effective (and environmentally friendly) way to use them is to first clean with oxygen bleach and then use the oxalic acid to brighten the deck.
Test Cleaners Before Use
Before committing to a particular deck cleaning chemical, first test it on a small area that is out of the way. Some cleaners can stain the deck's surface, so this allows you to make sure that it is safe to use.
Deck construction is an excellent way to add value to your home. However, to get the full benefits of your wooden deck, investing some time and effort into regular maintenance is best. It especially a good idea to clean your deck before and after harsh winter weather. The tips above can help you to keep your deck in pristine shape!
