Not for general maintenance but for bad scuffs or small burns such as those caused by a cigarette, or a stubborn stain that has been left to dry, the deck can be lightly sanded by hand with 40 grit sandpaper. This is also effective treatment when an area has worn smooth. Please make sure that when sanding your synthetic teak deck you follow the direction of the grain using short strokes. In some cases, sanding may make the area appear lighter in colour but exposure to sunlight or use of a heat gun on the area will blend the tone. Only sand by hand as using a power sander will warp the grain.
