Lawn equipment such as power mowers, trimmers and weed eaters can damage any fence posts—vinyl included. But since vinyl fencing consists of standardized components that are easily replaced, the damage is less of a problem than with alternative fencing materials that are variable and need to be carefully matched, or that need to be sanded, primed and painted. While all fencing is vulnerable to graffiti, vinyl is very easy to clean. In most cases, a little paint thinner does the job. In extreme cases, a pressure washer or some sandpaper may be required.
