Fix any damages that you noticed in step2, for chipped wood; you can use a palm sander if you have it. It would be better to purchase one to keep rather than renting one from the store.

Buy several sheets of sandpaper, grit 80 since you want that finish nice and beautiful. You would need to get on your hands and knees to feel any bumps on the wood and sand them flat.

If you encounter any mold or mildew while checking on each wooden panel, would need to treat that spot with a cleaner specifically designed to remove mildew. Read the instructions and apply accordingly.

Normally you would just need to use the cleanser and wait ten minutes for it to work, then just rinse clean. For any wooden panels that cannot be repaired or restored, then replace them respectively.

Homemade cleaner:

After you are done making the necessary repairs on your deck, it’s time to wash your deck with a homemade cleaner, grab a bucket to pour 2 cups of TSP for every 2 gallons of warm water, add a cup of oxygen bleach and mix well.

Use a deck brush with nylon or hard bristles and an adequately long handle to make it easier for you to scrub your deck clean. This would require some old-fashioned elbow grease.

Scrub the deck, leave for ten minutes then rinse clean, repeat if necessary. Scan the spaces in between the panels to make sure your brush got to any old leaves or debris and if needed clean with a putty knife.

When the time comes to rinse it, and you own a power washer, use that instead of your garden hose.

Commercial cleaner:

If you decided to purchase, a wood deck cleaner makes sure to read the instructions and follow each step respectively. Apply the wood deck cleaner, most cleaners will just require you to spray the cleaner on the deck; you can do that.

Spray the deck cleaner on the deck use paint rollers to evenly spread the cleaner on each wooden panel do not let the cleaner accumulate into puddles use the roller and spread it evenly as best as you can.

If you do not have paint rollers to spread the cleaner, you can use a mop with a sponge tip, or the deck brush you used earlier works too.
