Prepping Your Wood Deck – Cleaning

Dirty DeckExterior wood decking when left neglected oxidizes from the Ultra Violet rays from the sun. This will patina the exposed layer of wood cells turning the deck gray. Cleaning the deck first will a deck cleaner will remove this layer of graying wood cells while removing accumulated dirt, grime, mold, mildew, and algae.

Prepping your wood deck is the singular most important step when it comes to getting maximum performance out of your deck stain. Failure to prep and your stain will fail faster then it should and will not give the wood it’s natural beauty.

This article will go over the needed steps to properly clean your deck prior to applying the stain.

  1. Make sure that the deck is clear of all furniture and grills prior to starting.
  2. Decide first if you should use a deck cleaner or a deck stain stripper. Use a deck cleaner if the wood is gray and dirty. If you have am old deck stain that needs to be removed then you should use a deck stain stripper as the deck cleaner is not aggressive enough to remove stains.
  3. Pre-wet the deck first before applying the deck cleaner. Take precautions to wet all vegetation and the surrounding house. The majority of deck cleaners will not harm plants as long as you pre-wet and rinse off any residual cleaner that comes in contact with the plants.
  4. Wait about 5-15 minutes to let the cleaner activate. If needed, mist the deck with water to keep the cleaner from drying on hot days.
  5. Using a stiff scrub brush, starting agitating the deck until the wood comes clean. Using a pressure washer at 1000 psi or less will speed this process up.
  6. If any stubborn areas persist then repeat the process.
  7. After deck is thoroughly clean make sure to rinse the house, deck, plants, etc to remove all of the loosened grime.
  8. Using a Wood Deck Brightener will give the wood and added boost in appearance. The brightener neutralizes the deck cleaner and “brightens” the wood to a more natural state.
  9. Let wood dry a minimum of 24-48 hours before applying a deck stain or sealer.

    I stripped and brightened my cedar deck about 3 weeks ago now. Due to kids' events, work, and continual intermittent rainy weather, I have yet been unable to stain it. I will be using TWP 100 stain. What do I need to do at this point before staining? Should I be repeating any steps once it's sufficiently dry?

  2. Kitty says:

    If it is Hot sunny day do I need to wait 48 hours after applying brighrener before staining

    I have a newer deck that I am going to clean and stain. Should I sand before the cleaning or after?

    We're getting ready to strip/clean/brighten/stain a porch, deck, and gazebo–a lot of area. I have a one-gallon bottle of Flood Wood Cleaner and a one-gallon bottle of Wolman Deck & Fence Brightener, both from about four years ago, on hand. We will definitely need more product than that! If I use what I have on hand in addition to something like the Restore-A-Deck products, will the difference in performance (in terms of cleaning and brightening) be noticeable? We are trying to keep costs down but don't want to do anything that would jeopardize the results. This project is too expensive and too big for mistakes! Thanks for any help!

    My husband pressure washed our deck a week ago with deck cleaner. It left a film and fuzzies all over the deck. I have been sanding to get it clean and nice looking. My question is – do I have to redo the cleaning solution after sanding or can I wet it down and use the brightener? Thanks for your help.

  6. Jeff says:

    I stripped my cedar deck of the previous Wolman semitransparent stain, using their stripper. I sanded the fuzzies and it looks like new. Do i need to use a deck brightener, or can I stain it as is? If I use a deck brightener and apply a water based stain do I have to wait 24 hrs to stain, or can the deck still be slightly damp?

    I am about to stain my new deck this weekend and it is going to be pretty cold in Wisconsin. I plan to stain on Sunday when the high it 56F. Friday and Saturday both have a high of 50F. Should I clean my deck a few days earlier so that it has extra time to dry in the cold temperature? The other thing I need to consider is the white pine tree next to my deck is shedding its needles right now and may continue to drop after I clean the deck.

    Hello! I am in the process of cleaning a very large deck and am planning to stain it, but I only have a short time per day to work on it. I've noticed that the areas I cleaned 2 weeks ago are looking grayish (less so than before, but moreso than the newly-cleaned areas). I'm not sure what to do, since I can't change my schedule to move any more quickly, and I feel like I'm going to end up in an endless cycle of re-cleaning. What can I do about this? Can I stain parts of it at a time (i.e. clean one railing and stain it, and then clean the floor and stain that, etc.)? Any help would be appreciated. Thank you!

    • It is not really possible to do deck maintenance in stages like this and have it all turn out \”evenly\”. Best to do all the cleaning at once and stain all within 2-14 days after. Sorry but it will be very hard to do it the way you are doing it and have it turn out properly.

  9. Jamie says:

    If I have stripped the stain off my deck with Restore-a-Deck, but don't plan on restaining until spring (temperatures and rain are preventing me from wanting to right now), should I wait to brighten after a spring cleaning? I didn't know if I needed to brighten a certain amount of time after stripping or if it is okay to wait until spring when I stain.

    Thanks and great website! Really helped with my deck project :)
