PVC, or polyvinyl chloride, is a type of hard plastic. Commonly used in construction, PVC is the material of choice for items such as siding, plumbing, and fencing because it is lightweight, affordable and easy to maintain. All PVC fencing really requires is a periodic cleaning with soap and water to remove dirt and residue. While PVC is very durable, it does occasionally get stained. For example, direct contact with metal objects can leave unsightly rust stains on PVC. Fortunately, these can be easily removed with distilled white vinegar and a bit of elbow grease.


Step 1

Remove any metal objects at or near the site of the stain. Rust is caused by the oxidation of metal and therefore is not commonly associated with PVC. If there are no metal objects near the fence, the stain is probably from exposure to hard water, not rust.

Step 2

Spray the fence with water from a standard garden hose. This will remove any loose dust, dirt or debris. Use a nozzle to create adequate pressure or place your thumb over the end of the hose, partially covering the opening. By decreasing the available exit area you increase the velocity of the water.

Step 3

Mix 1 tsp. of liquid dish washing soap into 2 cups of water. Stir briskly to create soap suds. Apply this solution to the stained portion of the fence with a stiff-bristled brush. Scrub the affected area lightly using small, circular motions to lift the stain from the surface of the plastic. Rinse the area with clear water.


Step 4

Rub the rust stain with a sponge that has been soaked in distilled white vinegar. Apply light pressure to the sponge while scrubbing. Wipe the vinegar away with a wet cloth and repeat if necessary.
