Stain |
Remedy |
|
Mildew |
Clean the surface with a commercial deck cleaner/brightener. If it is not in liquid form, mix the powder concentrate with the recommended amount of water and apply with a garden sprayer, brush, or roller. Wait several minutes, then brush briskly with a stiff brush or broom. Rinse with a garden hose. Some cleaners may contain acids or chlorine, which can harm plants; check your label. |
|
Candle wax |
Saturate a rag with mineral spirits. Set the rag on the dried wax until it absorbs the wax. You may rub lightly. |
|
Barbecue stains (including grease and sauce) |
Scrub with a strong household detergent or water-rinsable automotive degreaser or carburetor cleaner. Rinse the area before it dries. |
|
Tannin |
Remove the black streaks of tannin-rich woods with a specially formulated tannin cleaner. |
|
Rust |
Apply a solution of water and 5 percent oxalic acid to the stain. Let it sit for several minutes, then rinse. |
|
Leaf stains |
Spot-scrub the area with a 1-to-1 solution of household bleach and water. |
|
Green algae or moss |
These stains are difficult to remove and usually reappear once the roots are formed in the wood, but you can temporarily eliminate them by scrubbing with a solution of 4 parts bleach to 1 part water. |
|
Sap |
Scrape excess material with a putty knife or steel wool. Wipe with turpentine. |
