As these organisms are very resilient, they can sustain themselves through a wide range of climatic conditions. If you are wondering how to remove green algae from the wood deck, there are some instructions that you must follow closely. These are listed below.
The first thing that you need to do when you want to remove algae from your wooden deck is to clear the area by moving all the furniture on the deck’s surface. In order for the wood deck to be cleaned well, all your deck chairs, tables, swings, or any such furniture or fixtures need to be removed and stored somewhere safe, away from the materials that you are going to use to remove algae and clean the wooden deck.
The acid or bleach-based cleaner can cause some long standing damage to all the outdoor furniture that you have if you let them remain on the wooden deck while you are cleaning.
To clean wooden decks effectively and thoroughly, it is important that the wooden surface has been prepared well for the materials that you are going to use on it. If the deck has been out of use for a while, it is probably going to have a lot of leaves, gravel, and other elements just lying around. You need to use a broom to sweep the entire wood deck vigorously. This will ensure that a large amount of dust and dirt is removed before you start.
Fill a bucket with warm water to about ¾ of its capacity. Then, add two cups of high-quality oxygen-based bleach to the water. You need to be very careful when you are dealing with chemicals like bleach, so make sure you are safe by wearing a mask, rubber gloves, and protective clothing.
Once you are sure that you have adequate protection, you need to get your hands on a good-quality scrubbing brush and use the bleach solution to move across the wood deck as you scrub the surface vigorously. This is a very important step in cleaning wooden decks and the bleach solution needs to be given some time—usually between 10 and 30 minutes—to start working. This is the chemical that will kill and remove algae and mold that has built up across your wood deck surface.
Once you are sure that you have given it enough time, rinse the entire surface using a garden hose.
Once you are done with the bleach, you will have to use a specialized deck cleaner to do a more in-depth cleaning of the wood deck. These cleaners are usually acid-based or bleach, so you can check which one suits your needs best.
Most of these deck cleaners have to be mixed with some amount of water before you can apply it to wood decks, so be sure to read all the instructions very carefully. It should be allowed to set for a while so that you can get rid of all the algae. Use the scrub brush again and give the wood deck a thorough cleaning.
Once you are satisfied with how clean your wood deck is looking, it is time to use your garden hose to give it a good rinse. This will be helpful in removing the cleaners and bleach, which can cause a good amount of damage if they are just left there. It is important to ensure that all parts of the wood deck and nearby areas are hosed down so that there is no cleaning solution left.
Pick up your broom once again and sweep the deck wood well so that there are no product or water pools left around on your deck. If there is water left around and on the deck, it will act as a breeding ground for algae all over again. Once the water pools and puddles have been swept away, you can just air dry the entire deck.
A good deck sealer can be a savior for people who want to keep their wood decks looking good as new and o avoid the growth of mold, mildew, or algae on the surface. Most good-quality deck sealers also provide UV protection.
If you have sealed your wood deck after cleaning it well, it is time for you to set it up again. Ensure that the deck wood is completely dry before you start putting all the furniture and other fixtures back on the deck and enjoy your summer out in the sun!
