Dirt and Debris
　Clean deck to remove dirt and debris. Soap, hot water and a soft bristle brush are all that is needed.

Markings
　All colored lines are permanent except white. We suggest using white chalk or baby powder. Scrubbing the area with hot soapy water with bleach may dislodge some of the chalk.

Visible Mill Markings
　The mill markings on the side of Sunnywood decking boards are required by building codes. With careful installation, most mill markings can be hidden. Visible mill markings can be lightened with acetone.

Water Spots/Leaf Staining
　Tannin leaching occurs in Sunywood and all wood based products naturally. Allow for at least 16 weeks of normal weathering. This process may be hastened through the use of a product containing oxalic or phosphoric acid commonly known as a Deck Brightener.

Pigment Staining
　During the weathering process, a small amount of surface pigmentation may wash off of the Sunywood surface, which may discolor neighboring surfaces. Remove with common rust cleaner.

Ice and Snow
　Calcium chloride or rock salt, available in many home centers, will melt ice on Sunywood decking.

Scuffs & Abrasions
　Will fade or disappear naturally after 12-16 weeks of weathering. This can be accelerated with a bleach-based deck wash followed by weathering.

Rust Stains, Ground-In Dirt and Grime
　Use a cleaning product containing oxalic or phosphoric acid base to lighten or remove the rust or dirt. Product may need to sit on stain 10-15 minutes.

Oil and Grease Stains
　Scrub in a household-degreasing agent as soon as the stain occurs. Rinse with hot water.

Berries and Wine Stains
　Mix bleach into hot water according to the bleach-packaging label. Scrub the stain lightly and rinse thoroughly. The stain may not disappear entirely.

Ink Stains
　Inks may be permanent. However, the stain may be lightened by scrubbing with hot soapy water. Rinse thoroughly.

Pressure Washer
　Sunywood does not recommend the use of a pressure washer. The use of a pressure washer with a greater than 1,500 PSI and/or applied closer than 10" from the deck surface could damage the decking surface and result in a loss of warranty coverage.

Mold
　Use conventional deck washes or cleaners that contain sodium hypochlorite (bleach) and detergent.Periodic cleaning (Spring and Fall) of your deck, even if it appears clean, is important to prevent the build-up of pollen/debris that can cause mold badly using.

Sanding
　Sunywood does not recommend sanding. Sanding will change the appearance of the surface of Sunywood material.
