How to Clean a Moldy Wooden Fence

I’m getting our outside “To Do” list out and we’re ready to tackle a project that is long overdue.

We live on a corner lot with a side yard, instead of a back yard, and around this side yard we have a wooden fence, that was here when we bought the house almost two years ago. We’ve had a lot of conversations about this fence in those two years…should it stay, should it go, should we take down part of it, should I secretly take a sledgehammer to it when hubs is away on business…you get the idea. I’ve never liked the fence but after two years I do see the benefits of the privacy it provides as we are on a busy road with people walking by all the time.

We’ve done a few things to improve the look of the fence, including taking down the gate, that hung crooked and would never close, and removing a funky little roof on one section of the fence, we think the previous owners stored their garbage cans under it. But it was time to get serious about the ugly mold covering most of the fence, so we recently spent a Saturday cleaning it.

This was one of those projects that really needed to get done but was put off so many times because we thought it would take hours to do. The fence was looking so bad though, that we couldn’t ignore it anymore and got to work.

First we tried a few easy things, like taking a scrub brush and some warm soapy water to it, but it didn’t do a thing to the mold. Next we tried some bleach and water in a lawn and garden spray bottle, but that did nothing to remove the mold either so it was time to bring in the big guns.

Cleaning a Moldy Wooden Fence | chatfieldcourt.comWe ended up using liquid chlorine (typically used in swimming pools) that was purchased from Home Depot. This stuff is potent so we diluted it with water in the sprayer and applied it to the fence. A good tip to remember is that when you spray the solution on the fence you want to be sure to start at the bottom and work your way up (working from the top down could result in streaks). You also want to be sure to wear some old clothes and protective eyewear. The solution worked like magic and the mold disappeared almost immediately.

It took no time to spray the whole fence and once it was dry it looked almost brand new. There’s still a few stubborn spots we need to scrub, but it looks 100% better.

Do you have a “To Do” list? Does it make you happy to cross completed projects off of it too?

    Nice job Kristi! Yes, I have a “To Do”, but I keep adding and it seems to get longer and longer instead of shorter! Ha! Gotta send you those photos I talked about. I haven’t been feeling up to par for a few days. I think I caught a bug. It doesn’t seem to knock me down completely, just don’t feel like to doing anything or eating too much. Hope it gets better soon because I’m off next week and going to tackle that “To Do” list!

      My list is the same MJ…growing instead of shrinking. Sorry you haven’t been feeling well. Hopefully you’ll be back on track next week. I bet you are ready for some time off. Yay! 🙂

    Looks great Kristi. That is not a fun job, but it looks like you found a way to make it easier. We have a corner lot, too, and a big fence. I wasn’t fond of the idea initially, but I do like the privacy!

      Thanks Kim. It wasn’t a fun job but once we figured out how to remove the mold, it went pretty quick.

    Hi Kristi 🙂

    The fence looks great!

    Oh and I’m a small town girl now, but I grew up outside of Los Angeles and when my parents moved us to the country I was NOT happy lol I want to be close to town, but the city just doesn’t speak to me anymore. It’s funny how things change 😉

    Did it do damage to the plants and grass? Did you cover them up with a tarp? Would like to do this but concerned about the plants.

      I was concerned too but we had no damage to any of my plants or grass. I did clean the fence before my perennials came up, but the few bushes that I have in this area did fine. We also made sure to really hose down the area we worked in after cleaning. Hope this answers your questions.

    How much did you delude chlorine?

      Thanks for your question Deb. We used equal parts of chlorine and water. We tried a lesser amount but it just wouldn’t cut it. Just remember to hose down the area that the mixture was used in after you finished the fence. Hope that helps.

    We have a painted wood deck that has a green mold in areas. Do you think your chlorine mixture would work on that?

      Hi, Mariya! We have used the same mixture on our wooden deck and it definitely works. It will bleach the wood a bit, so be prepared for that.

          Thanks Kristi. The perennials around the fence were hostas. So easy to care for and were huge by the end of summer. Generally a shade loving plant. 🙂

            Thanks so much Kristi !!
            Thats great to know as I have a lot of shade as well down here in Louisiana ? Also, what is the tall little skinny green plant between the hostas? Love that one too 🙂
            Thanks so much ,
            Kristi ?

            Hi Kristi. I believe that is a boxwood in between the hosta. I wanted to see a little green in the winter once the hosta died away and they were great for that but I planted them a little too close together. Hope that helps. 🙂 Have a great weekend.
