Woodrich Wood Cleaning & Brightening Restoration Kit 750

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.  

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

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.

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.

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.

(You must also follow safety procedures, protect adjacent surfaces from over spray and etc.)  

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.

No, this product is not an effective paint remover.

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.

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

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.
