1.The first thing you should do when cleaning your fence is to hose it down to get rid of the dirt and grime that can easily be removed with a little water. Next utilize a brush with the garden hose to get rid of looser grime. After you do this you will be able to assess your true problem areas and where the dirt and grime is the heaviest.
2.The best way to clean your fence is to create a simple solution yourself. Just add a cup of a safe cleaning agent like Simple Green to a gallon of water. If the fence is exceptionally dirty you can make the solution stronger. Apply the solution to the fence and let it sit for a few minutes then scrub it with a soft brush and cloth until the stains are removed. If the stains are significant you can use a solution that contains bleach and water but be careful, the bleach might change the color of the fence creating a bigger problem. Always test any cleaning solution before using it to make sure it will not damage your fence.
3.Your vinyl fence really doesn’t need to be cleaned more than once per year, twice if you live in an area where it gets easily dirty from mud or mildew. Generally the advice is to clean it in the spring, after snow has melted from around it but you can also clean it in the fall. It is all about the weather; no one wants to be outside with a hose in the cold!
