Removing Algae and Other Build Up from a Wooden Dock

As the spring and summer months ease by, dirt, and other grim, tend to build up on your dock – leaving room for algae, moss, and mold to grow. This is why it is essential to have a cleaning routine for the deck in order to promote a longer life span.

So, what is green algae and what encourages growth on your dock?

Algae is a simple, non-flowering, aquatic plant that thrives in a sunny, damp environment. It typically causes a green film over a deck and poses as a danger to people walking over it due to how slimy it becomes once wet. Because algae is unlike an average stain and will grow pretty quickly, it is important to treat the issue as soon as it is noticed to prevent further growth. The two main factors to be mindful of in cleaning your dock are as follows…

  • Debris – as leaves and other natural things land on the dock, it is important to sweep them away as soon as possible. They tend to create the perfect breeding ground for algae, mold, and mildew.
  • Moisture – does the rain cause puddles to form on your deck? If so, use a broom to sweep the water away. Moisture and sunlight are the two main causes of algae growth, so it is important to incorporate this technique into the overall care of your dock.

DIY Cleaning Solutions for your Deck:

  • Moss and Algae Removal Products – in a hurry but want to get cleaning? There are quite a few products on the market that are designed to help remove these pests from your dock. Although they are a bit more expensive than a household product, they will get the job done.
  • Hydrogen Peroxide – almost all of us have this product lying around the house somewhere. Hydrogen peroxide is an excellent way to lift the algae off the deck however, keep in mind that it is not a long-term solution and will not kill the growth entirely.
  • White Distilled Vinegar & Water – combine vinegar and water create a safe mixture to be used in scrubbing the algae off your deck.
  • Pressure Washing – if you’re against using products or chemicals on your deck, pressure washing is a safe way to get the job done. Make sure you have the machine set to where it is not using too much pressure. Afterall, too much pressure can result in damage to the soft wood.

Although there is no magic solution in preventing algae from forming entirely, there are ways to slow the growth and/or prevent it from spreading. It is important to keep in mind that algae tend to develop quickly, so the sooner the problem is dealt with, the better. Considering that algae thrives in a damp environment, sealing your dock with a water repellent will aid in the prevention of growth. Along with this, routine maintenance will increase the life span of your dock and make it a fun, safe, place for everyone to hangout!
