Vinyl fence brings style and crispness to your yard. Along with bringing a modern and glossy look of vinyl to your house, it has the benefit of withstanding weather conditions more than other wood fences. If you installed it years ago and noticed dirt and milder on the fence, it may be time to pressure wash it. It can collect algae over time and feed on the surrounding plants. Although you do not have to worry about the damage as vinyl is a non-porous material, however, it can become so dirty to even look at it.
