If you want to clean and properly seal a deck, follow these tips from maid service scottsdale. Pay special attention to the distances between boards. Leaves will rot in there and rest on the joists, finally rotting the boards. Use a putty knife to clean the crevices.

Clean the surface of the wood. There Are Lots of products on the Current Market, or You can use bleach, reduce half and half with warm water, and a scrub brush. This is great for small areas and will work wonders for algae and mildew and the like. (Directly, undiluted bleach isn't a good idea for a deck, and it should not sit there for any length of time)

For larger areas, rent or buy a pressure washer. Spray the bleach/water Mixture on the boards first and let it soak in for some time before pressure washing. Ensure that you cover up shrubs and plants before you start spraying bleach.

Once your deck is clean, use a redwood stain or a waterproofing deck Sealer, which will repel water and make the deck last longer. To apply the Sealer, buy a pad with a little reservoir and then brush it on. Or use a foam roller. Go over the entire deck surface with the sealer.
