RAD CLEANERdefaultRestore A Deck Cleaner Instructions and How To Tips

Keeping your wooden deck in good condition is without a doubt crucial to both its appearance and lifespan. Nothing looks worse and deteriorates more quickly than a neglected deck. Many deck owners have opted to do their own deck maintenance.

Restore A Deck cleaner is a specifically designed two-part system that is best used to clean and prep a wood deck prior to resealing it. The Restore A Deck cleaner system consists of a wood cleaner that will remove dirt, grime, mold, mildew, and grayed wood fibers. Step 2 of RAD Cleaner is a wood brightener that corrects the pH of the wood and brightens it up prior to applying a wood stain or sealer.

To clean a deck using the Restore A Deck system follow these easy step-by-step instructions.

1. Be sure air temperatures or between 45-90 degrees. Remove all furnishings from the deck and the surrounding area.

2. Though Restore A Deck is Eco-Friendly it is still a good idea to cover sensitive plants and shrubbery or pre-wet them with fresh water. Use plastic to cover doors and windows in the surrounding area.

3. Follow the Restore A Deck instructions to mix the Step 1 Cleaner in a clean bucket until all crystals are dissolved and transfer to sprayer to avoid clogging of sprayer inlet tube.

4. Lightly spray the wood deck with water. Use a pump sprayer or scrub brush to apply RAD Cleaner to the wood. Allow the cleaner to dwell for 5-15 minutes. Keep the deck wet by misting with water during the dwell time. If using a pump sprayer please make sure that no undissolved powder is poured into the sprayer. It will get clogged!

5. Hand scrub or use a pressure wash to remove dirt, grime, and graying from the wood surface. Do not use excessive pressure. Pressure washing at 1500 PSI is much more effective and easier.

6. Once cleaned, rinse the wood deck and the surrounding plants, windows, house siding, etc.

7. While the deck is still wet from rinsing, apply the Restore A Deck Wood Brightener (Step 2).

8. Blend the RAD Wood Brightener by following the product’s instructions and apply with a pump sprayer. Allow the brightener to dwell for 10 minutes then rinse off. No need to having scrub or pressure wash the RAD Brightener. Make sure to rinse the RAD Brightener thoroughly for 20 minutes until all soap suds are removed after the 10 minutes dwell time.

Note that the RAD cleaner is not intended for removing old deck stains or sealers. Please see Restore A Deck Stain Stripper when dealing with existing stains.

    We stained our deck floor last June with RAD Solid. The railings and posts were replaced at the same time. I want to stain the rails and post but am concerned that it will damage the beautiful finish on the floor boards. Will it damage the floor? How can I prevent this? Plastic sheeting seems like it might trap the cleaner/brightener when I am rinsing.

      It should not harm the solid stain on the floor. Prewet and rinse well any over spray.

    in sept 2019 to my 15 year old untreated deck using all your products i cleaned, then brightened, and applied two coats semi transparent dark walnut, with semi cedar on border. Did not overcoat it. Looked great (see pix), but 6 months later when i washed it with dawn dish soap it seemed like it washed or lightened the stain out in some spots (not all, just some.) And its worse now (2nd pix) What went wrong? Now i want to fix it, what should i do? i want to apply same color and product. No need to strip first? only clean and not brighten? one or two coats? help! don't want to repeat any mistakes. i followed all your instructions the first time.

      Use the RAD cleaner and then pressure wash. Brightener after. Apply one coat of the RAD Stain. it is normal to have to re-coat every 2 years.

        Shelene · 06/14/2021
        thanks. Why do i have to use the brightener again? Is dawn dish soap a safe product to use to clean it next spring? if not, what is a safe cleaning product i can use next spring after i've done this maintenance coat this summer?

          RAD Products · 06/14/2021
          You always have to brighten after you clean to neutralize. Just use water to clean with a little bit of dish soap. Not anything too strong or aggressive.

            but in your instructions it says that if you are applying a maintenance coat you only have to clean and not brighten it-so i am confused why you are suggesting i need to use the brightener again. please clarify and explain why you are suggesting something different than the instructions. thanks

              It is used to neutralize the cleaner when you have bare wood as you do.

    I cleaned and brightened my 1 yr old redwood deck with RAD.  I used a soft bristle brush and pressure washer with the cleaner.  The deck looked great after I cleaned it, however when I started to stain it with Armstrong Clark Sierra Redwood Semi-Transparent Stain I noticed some boards had areas looked blotchy.  Upon closer inspection there were other boards that had this appearance after the cleaning and brightening.  Do you have any suggestions on how to prevent this appearance on the boards I haven't stained yet?

      In most cases, use the Cleaner. You would strip if it was uneven. Brightener after.

    2 questions Do you rinse the brightner with a pressure washer or garden hose Will the cleaner and brightener damage a marble insert we have in the decking

      Pressure washer. Not sure about the marble. Probably not but best to cover just in case.

    I have two 400 sf decks one above the other. We recently purchased the 18 year old house in Bend, OR and I believe it has the original decks. The climate here is high desert with little rain and 300 days of sunshine. The 1st picture shows the lower deck which doesn't look like its has been sealed (water sits, but doesn't bead). The 2nd picture shows the Upper Deck with an unknown sealer on it and the water beads. SORRY PICTURES WOULDN'T UPLOAD.
    I bought the cleaner, brightener and semi-transparent natural stain. After reading more on your website, it appears I must strip the sealed upper deck with before cleaning, brightening and staining.
    Since the working on the upper deck will drip down on the lower deck, what is your recommendation for the order in which I should refinish? The upper deck is the one most used and visible.

      We would need to see pictures for prep help. If they did not load the file size was too large. Try saving as smaller. Always start from the top, then down.

    I have a deck that I plan on using the RAD solid stain on. I've already sanded it completely, removing old peeling behr deck-over that was on it. I plan on using the RAD cleaner on it next. Will I still need to use the brighter as well even though I'll be coating it with solid stain after, which would hide the brightened wood? Or is this still necessary to assure a proper surface for the stain to work into?

      RAD Products · 03/21/2021
      It always helps to neutralize a deck cleaner or deck stripper with the brightener, so there are not any issues with chemical reactions with the stain.

    I cleaned, brightened, and applied the Dark Walnut semi-transparent stain last year. If I understand correctly, I can apply a maintenance coat this year, instead of stripping it and starting the process all over. Is that correct?
    So, would this year's process be:
    1) Apply Cleaner and power wash
    2) While the wood is still wet, apply one coat of Dark Walnut Semi-Transparent stain

    Or do i need to apply 2 coats?

    Hello!

    We stained And sealed our deck a year ago but the moisture this summer created a mold and black stains on our deck. We plan on just cleaning the deck and to remove dirt and black mold stains as the deck stain is in good shape. Are we good to use the cleaner and brighter if we plan to not stain again?

    Thanks!

        No did not use brightener yet. I did go over the darker spots with cleaner, not sure if it is better, was to wet and getting dark. Had close to 200 ft of railing to do. I can brighten tomorrow. Do I need to re-wet with water before doing the brightener? Also have little bit of fuzzies on railing. Do I sand them down? Sorry to dark for pictures now.

        Deck floor will be in a few days.

          RAD Products · 09/29/2020
          The cleaner darkens the wood by raising the pH balance. This is normal and why you have to brighten the wood after and is supposed to go on as soon as you are done with the cleaner or stripper for the best results. Rewet and brighten as soon as you can. You can sand fuzzies if needed.

      You cannot "spot" fix. You would have to redo all. At this point in the year, probably just best to wait until Spring.

    We are wanting to stain our 300 sq ft deck. We power washed with just water before your product arrived. It has never been treated and is about 4 years old. Some of the deck is covered and some is not. Several of the areas that are not have green mildew/mold that your cleaner and brighter were not able to remove. Do you have any suggestions on how to remove this from those areas? We finally had a dry spell and are hoping to get it done before winter!

      If the green is deep in the wood grain then it will not come out. The prep products work to remove what it is on or near the surface.

    Maybe you know the answer to this:
    Your instructions step 5. States a 1500 psi washer will be fine. Is a 2700 psi too much even with the nozzle that lowers the pressure?
    • We will reply to your comment shortly
      RAD Products · 09/07/2020
      You can use a stronger pressure wash, just back off and wash 6-10 inches from the wood, it will drop the pressure in 1/2.

    Hello, I just installed two new boards on a deck I already replaced all of the boards on. These two are discolored, possibly by mildew. Since I want to ensure these stains are removable before waiting months to prep and apply a semi transparent, only to find out its not coming off, I wondered if it spot treatable? Any advice is appreciated. Thank you.

              Hi, I only had Oxy Clean, thinking it would be ok as a less abrasive solution, and was left with this. Some mildew still there, and despite my rinsing of the area these discoloration spots. Is this what it will all look like when I clean and brighten, or did the OxyClean stain it like a direct bleach solution would have? Thank you.

          We used RAD cleaner and in a few places there is still a slight oil sheen on the wash water. Do we need to do it again? We used Armstrong Clark Redwood Tone and are trying to bring it to a state where we can re-stain.
