Cleaning your deck with 30 SECONDS Outdoor Cleaner

If you live in an area that gets rain (okay, maybe that's everywhere!) and you have a deck, then you'll want to know the best way to clean your deck. First, you'll want to choose the right product.  Here's a comparison of 30 SECONDS Outdoor Cleaner and some common other products:


BleachCommon household bleach (sodium hypochlorite) will only clean the surface of the deck. Bleach will harm plants and lawns.   Bleach is just a surface cleaner so any results that you may see from cleaning your deck with bleach will be short-term.

Pressure Washing

You might think that pressure washing is the best since using powerful machines is great fun!  However, pressure washing can cause long term damage to your deck.  The problems pressure washing can cause are:pressure washing

  • removes natural oils in the wood which makes wood more brittle
  • causes wood to dry quickly which causes warping
  • loosens nails as the wood expands
  • removes loose material and leaves gaps in the wood which open up more with sun and water
  • creates splinters and loose wood fibers

Many pressure-washer salespeople and contractors will tell you that it's safe to pressure wash when you use a low-pressure setting.  But even on low-pressure setting, your deck can be damaged.

Last summer we cleaned and stained our large deck and it wasn’t long before algae started growing. Can 30-second cleaner be used on a 9 month old stained deck? It was stained twice and we love the looks and the color, so wanted to preserve what is already there.

Hello Becky,

Thank you for contacting 30 SECONDS Outdoor Cleaners about cleaning your new deck. We would recommend testing first. Apply a small amount of cleaner to an inconspicuous area, let sit about 5 minutes, and rinse to see results.

I bough the gallon jug you attach to the hose. Sprayed it on a dry surface, let set as instructed, then power washed it. The deck looks exactly the same as before. Dirt and mildew is still there. Can I use it straight? Seems like all I was doing was spraying the deck with water.

If I use a larger ratio of 30 sec in my sprayer will it be effective if used while raining?

Hi Connie,
We are sorry to hear that you didn’t get great results. We usually find that using the cleaner full strength isn’t the answer to better results. GIve us a call at 503-669-1953 and we can troubleshoot with you to find the best answer. We hope to hear from you soon!

Hi Debra,
Applying 30 SECONDS in the rain not only dilutes the cleaner. The stains that you’re looking to clean will be saturated with water, instead of saturated with cleaner. It really is best to start with a dry surface for good results with minimal scrubbing. We hope this helps!
