  1. Darlene Kenny

    We have a 4 year old cedar and PT deck that we had stained 3 years ago. The stain color, which we never really cared for, had become faded & made the deck appear old and dirty. I had researched deck cleaning prducts on line & found the Woodrich brand among many. I showed my husband the impressive results on your how to videos. Frankly he was skeptical and told me not to “believe everything you see on the internet”. Well, we went ahead and ordered the producy while husband grumbled and told me we’re wasting our money. Several days later, we applied the EFC38 with a garden sprayer and a light powered pressure washer. I can only say that the results were absolutely amazing! Our deck looks brand new again and even the old stain came out. My husband is still not sure how or why it worked so well, but you sure have made a believer out of him!
    The deck brightener was equally easy to use and apply.
    Thanks again for such an amazing and easy to work with product.
    Completely satisfied!

    Not only did the products that I ordered come quickly, the person that fulfilled the order noticed that if I ordered my products as part of a kit rather than separately, I was eligible for free shipping. They changed my order to make that happen for me! EXCELLENT service! I will certainly be ordering from them again.

  • Do I have to apply the brightener immediately after cleaning with EFC-38? What is the maximum time I can wait between cleaner and brightener?

    You can apply the brightener right away after cleaning.  If there are puddles of water, try to broom those off before applying the brightener.  There is no maximum amount of time you can wait, as long as you apply the brightener at some point before you stain.


  • How soon do I have to apply the stain after using the cleaner and brightener? Can I wait a few days?

    Yes, you can usually wait up to about three weeks before the sun will start causing the wood to lost its natural color.

  • Should the wood be dry, damp or wet before applying EFC-38?

    It is okay if the wood is damp (with no puddles) or dry when applying EFC-38.  The cleaner could become diluted if the wood has a lot of puddles.  Wood that is in the direct sun can become hot to the touch.  It is okay to mist the wood with a little water to cool it off before applying the EFC-38.  This will help the cleaner stay wet and active longer.

  • Your products are great! Can I use them to clean my concrete garage floor?

    HD-80 and EFC-38 are both very effective cleaners for concrete and hard surfaces.

    Of course you want to follow all of the same safety precautions as when they are used for wood restoration.

    Citralic Brightener/Neutralizer will effectively remove rust and other mineral stains from concrete.

    For severe concrete stains, you can wet the area and then grind in some of the dry Citralic powder making a thin paste.  Allow that paste to dry on the surface and then rinse away.  Repeat as necessary.

  • What is the step by step process for the EFC-80 kit(EFC-38 HD-80)

    There are two restoration kits available.  One of them comes with  the EFC-38, Environmentally Friendly Cleaner and mild stripper.  The other comes with the HD-80 Heavy Duty Stripper.  They both come with the Citralic Brightener/Neutralizer.

    The basic process is the same whichever combination you choose.  For detailed information, you can find a complete how to video here:  https://woodrichbrand.com/videos/

    In the most basic terms the steps are as follows:

    Mix either the EFC-38 or the HD-80 with water at 2/3 cup of powder to 1 gallon water.

    Pour into a Pump Style Garden Sprayer and apply to the surfaces you intend to restore.

    Perform a scratch test (in several locations) with the scratch stick provided or a stick from the yard to determine when it is time to power wash.

    A successful scratch test will allow you to easily expose fresh clean wood with gentle pressure.

    The material you are trying to remove should be about the consistency of pudding.

    When you have success each time you test, its time to power wash.

    Gently power wash all of the surfaces you intend to restore.

    When you have finished power washing it is time to apply the brightener/neutralizer.

    Mix and apply the brightener/neutralizer the same as you did with the first step.

    2/3 cup per gallon of water, mix in bucket, pour into pump sprayer and apply.

    Allow the brightener to sit on the wood at least 5 min, longer doesn’t hurt and it doesn’t matter if it dries on the wood.

    Give the wood a final rinse.  For this step you can use either a garden hose or a power washer.

    Allow the wood to dry and it is ready to stain.

  • Will this remove paint from aluminum Anderson windows?

    This product will not remove paint that is in good condition. If the aluminum windows are well aged and heavily oxidized, the cleaner may remove some of the surface oxidation. Thus, leaving what looks like either clean or faded areas.

  • Does EFC-38 remove paint?

    No, this product is not an effective paint remover.

  • Will EFC-38 remove sikkens cetol srd stain?

    No, HD-80 would be a better choice for that finish removal. Sample test kits are available to help you determine the required product dwell time.

  • Would this work for cleaning logs in a Log Cabin?

    Yes. EFC-38 is a perfect choice for restoring the weathered exterior of log cabins.

  • Our pressure washer can be used to apply cleaning products at low pressure. Can this product be used with a pressure washer if mixed right?

    This product is designed to be mixed with water and then applied at “full strength” using a pump-up garden sprayer. Injecting the solution using a power washer would dilute the product too much.

  • We stained our deck last summer, will this take the stain off? That's what I'm wanting it to do...

    It depends on what type of stain it is. This product will remove most true oil based stains and sealers. We also offer a Heavy Duty Stripper called HD-80, for solid stains and other hard to remove finishes.

  • Can HD-80 be used on other surfaces?

    HD-80 can be used to clean concrete, vinyl siding, brick, Trex and PVC.  You can also use EFC-38 as a safe roof cleaner

  • Do you also need a neutralizer after use of this product before staining?

    This product is a kit that comes with both the cleaner and the neutralizer. The green label product is a the brightener/neutralizer.

  • Is this required for new wood?

    It is not always required that you use this product(s) before staining. It depends on the type of wood and its condition. As well as the type of stain you will be applying to the wood.

    You can test your wood to see if it will readily accept stain by sprinkling the surface with water. If the water absorbs quickly into the wood, it is likely that the wood will also accept stain. This is so if you are using a stain that is compatible with the new wood application. Check if the water stands on the surface or beads up when you sprinkle water on the wood. If so, we recommended that you go through the cleaning and brightening process before applying a stain. It is also a good idea to use the cleaner and brightener. That is if you believe your new wood has been outside long enough to be exposed to pollen. Pollen is an excellent food source for mold and mildew.

    Finally, if your new wood has been outside long enough to begin turning grey, it is recommended that you use the cleaner and brightener to remove the dead grey wood fibers on the surface. So that your stain finishes evenly and without splotches. 

  • Does it remove stains left by potted plants?

    Each potted plant stain is different so it is difficult to answer this question directly (absolutely). Most likely yes, following the two step process will remove the stain left by a potted plant. Potted plant stains are usually one or a combination of dirt, “the green stuff” and fertilizer stains. The first will work to deep clean and help remove the dirt and organics. The second step will neutralize the wood and brighten any discoloration caused by contact with fertilizer that has leached from the potted plant. Sometimes potted plant stains can be stubborn and require more than one application of the cleaner and/or brightener. There is a sample test kit available if you prefer to test the efficacy of the products before you purchase enough for the entire job. 

  • Can this product be applied with a tank sprayer? I understand that I may need to filter first with a fine mesh filter bag.

    Yes. It can so long as the sprayer is compatible with acid. Most sprayers are.

  • Is EFC-38 harmful to humans or pets?

    Not harmful for pets if you use common sense and handle it properly.  EFC-38 was designed in order to be safe for the user and for the environment.

  • Will EFC-38 harm plants or grass?

    Nope, unless they are extremely delicate such as lacy ferns or soft petel flowers and they are in direct sunlight.  In such cases the water causes the sun to burn the plants.  Shake the excess water off to prevent burning.

  • Do I always have to use a Brightener/Neutralizer after I use EFC-38?

    No, EFC-38 finishes off close to neutral.  As long as you rinse well you do not have to use a neutralizer.  You may wish to brighten that extra bit to help make your work stand out among the competition.

  • The wood has turned dark after treatment! How do I get it to lighten up?

    Use Citralic Brightener/Neutralizer in order to brighten up the wood.

  • Will EFC-38 remove mold & mildew or should I add bleach?

    In most cases EFC-38 will easily remove mold and mildew.  You should see it work drastically when it comes in contact with mold or mildew.   If there is an extreme build up of mold and mildew you can apply additional EFC-38 to fully eradicate the infestation. (NEVER mix bleach with EFC-38)

  • What if I can't see the wood under a solid color stain? How do I tell if EFC-38 has gone through all the layers?

    If you are working on a solid color stain you should be using HD-80.  EFC-38 is only going to make the finish nice and clean.

  • How long does EFC-38 take to work?

    It is going to do it’s job in about 15 min.  If you have a stubborn finnish you may allow for additional dwell time keeping the surface wet.

  • How do I know when EFC-38 is working?

    The coating will change color and any mold or mildew should activly fizz up and turn white.  Use a scratch test to determine when the existing finish has been fully emulsified and is ready to strip.

  • What if I mix too much and have more than is needed for the job, will any left over EFC-38 go bad?

    Use EFC-38 within a couple of hours from the time of mixing.  Beyond that, it loses its effectiveness as a stripper.  You should also take care to keep the powder dry when you store it.  The shelf life of the dry powder is 6 months so be sure to keep your supply fresh.

  • How much EFC-38 should I use per gallon?

    Mix 8 oz (1/2 LB) per gallon of water for full stregnth.  In dry measure that is about 2/3 cup.  You can then dilute up to 4 to 1 with water depending on the job at hand.

  • What finishes will EFC-38 remove?

    EFC-38 works on removing oil-based finishes such as TWP, READY SEAL, WOLMAN, OLYMPIC, CUPRINOL and other semi-transparent finishes.

  • Is EFC-38 different than a percarbonate cleaner?

    EFC-38 contains a percarbonate, but is not like a straight percarbonate cleaner.  EFC-38 was designed to remove aged and failing oil based wood finishes.  It will perform many jobs that a percabonate cleaner can not do.  EFC-38 is safe to use and makes an excellent tool for wood restoration.
