How to Clean a Fence

This video is primarily focused on how to clean vinyl fences, in this case, our line of Certainteed Bufftech Vinyl Fences. The simple solution talked about in the video was sourced from Bufftech’s Care & Maintenance instructions which you can also find on our website along with specific instructions on cleaning other types of fence as well.

Be sure to take extra care when cleaning fences with a power washer. Vinyl fences have the potential to crack and shatter when faced with high pressure. Excessive pressure could cause wooden fences to break apart and splinter. Ornamental fences may experience paint chipping if the pressure is too high as well. If you notice that your fence is not coming clean, do not increase the water pressure, rather seek a mildew remover from your local convenience store.

Here is the simple solution:

1/3 cup of detergent (ex. Tide)
2/3 cup of trisodium phosphate (TSP) (ex. Soilax)
1 quart of 5% sodium hypochlorite (ex. Clorox)
3 quarts of water

One thing to pay close attention to is signs of artillery fungus. Typically found in mulch, artillery fungus can wreak havoc on solid surfaces like fences, siding, decks, and other solid structures. The fungus explodes causing small dark colored specs to attach to surrounding surfaces. If you notice this on your fences or surrounding structures, be sure to wash it sooner rather than later since it could cause permanent discoloration. Adam, suggested using bagged mulch to help fend off this issue or use alternatives such as decorative rocks. If you choose to still use mulch, seek advice from lawn and garden experts. They will be able to provide you with specific instructions on how to care for your exact type of mulch. It also helps to stir up the mulch on a regular basis to inhibit the growth of the fungus.
