How To Clean Your Dirty Deck To Make It As Good As New

 Removing a slimy green film from your deck couldn't be easier.  In this post, Jenn shares how she was able to remove that film from her back deck by using 3 items in no time at all.  She also included a free checklist so you can do this yourself.  #cleaning #outdoormaintenance #deckmaintenance #removemoss #homemaintenance

I live in the pacific northwest and that means during the fall and winter we receive a lot of rain.  When I say a lot, I'm not exaggerating we're talking 2-3 inches a day.

The other day the rain had cleared (for a short time) and I decided that I wanted to do a little bit of yard work in the backyard.  The third step I took onto our deck caused me to bite it.  It was a bloopers moment that I'm so glad no one witnessed me sliding, falling, and bouncing three times...

The problem was with all of the rain that we've received over the past 5 months has allowed a nice layer of green slime to form on our deck.  This is a common problem for anyone who lives in a rainy climate.

The combo of short rainy dark days causes moss to duplicate like I've never seen before.

It was past time for the deck to be cleaned so I got to it.  In this post, I'm going to share with you how I was able to take my slimy, moss-covered deck and make it look as good as new with only 2 ingredients (that most everyone has at home already), a scrub brush, and a little bit of elbow grease.

Obviously, the idea of cleaning your deck makes taking your kids to the dentist seem like a day at the park.  

It's important not to neglect areas of your home because they will cost you in the long run.  This is our second deck because I didn't do anything with it.  We didn't reseal it or clean it.  We took our deck for granted and then we ended up with a deck that was rotting away.

Since we invested so much time, money, sweat, blood, and yes a TON of tears I want to make sure our deck lasts and lasts.

The good news is, cleaning the deck cost me under $10.  All I needed was a Costco size thing of baking soda, some water, and a scrub brush.

I put together a free checklist to help you take the same steps I took to clean my deck.  You can download it by clicking the button below.

Now I'd like to walk you through the steps I took to quickly clean the deck.

Clear it out

The first thing I did was cleared off the deck.  Since it was January the deck was pretty much empty.  Our furniture and BBQ were packed away so they were clear of the elements.

As you can see below, the deck started turning a green color...

As you can see, this is exactly why I bit it.  The entire deck was covered in this green slimy film.

Wet it down & work in sections

Once the deck was clear, I hosed down the deck making sure the deck was wet.

Then, working in sections I sprinkled some baking soda and then started scrubbing.


I found that if I didn't work in sections the baking soda would dissolve and be washed away when I rinsed the sections.

The other great thing I found working in sections is I could see how nice the deck looked.


As you can see, the scrubbing really help remove the green film quickly.  

You can also see the wood going back to its "normal" color.


Here's another shot of how much better the deck looks.


Here's an after picture of what the deck looked like.  

With a little bit of time and elbow grease, I was able to remove the green slime from my deck and I'm happy to report it's safe to walk on the deck.  

This might not be something that needs to be done in all climates but if your area gets a lot of rain then this is probably a good idea.

Once the weather turns to more sun and less rain I'll be ready to seal and stain the deck again.

If you are in need of scrubbing your deck you can take the same steps I took.  I've put a checklist together for you so you can clean your deck with ease.
