How to clean cedar safely, effectively and without bleach:

1. Determine your coverage area. Wash Safe Cedar Wash Wood Cleaner is an organic concentrate. Our smallest size bottle (3LB) makes about 12 gallons when mixed with water. One gallon covers 250 square feet and 12 gallons covers 3,000. The average home is approximately 30 squares, meaning that their roof is 3,000 square feet so use that as your guide and check our our coverage information listed in the product details so you can determine the right amount for your project. If it's a stubborn area, double the strength to remove tough stains.

2. Add 1/2 cup of Wash Safe Cedar Wash Wood Cleaner per gallon of water and mix well, stirring consistently for 15 minutes prior to use. Yes, it's a lot of mixing (nice little workout there) but this will get the formula as activated and powerful as possible for the task ahead. Never mix with other cleaners!

3. Apply to surface with garden style pump/ spray system. 

4. Clean cedar with a scrub brush and hose off or use a pressure washer system to rinse surface clean. Check out our recommendations below for what you should use. 

5. To keep surface clean when completed, seal with our Wash Safe Cedar Seal.

What formula to use when cleaning cedar:

John's Cedar Wash does not use bleach! Cedar Wash comes in a powdered form that when mixed with water creates millions of tiny little bubbles; these bubbles loosen all the old dead wood particles to be easily washed off along with mold and mildew stains. The secret is the natural adhesives that we added to keep the product on vertical or steep pitched surfaces long enough to clean before running off. If your cedar had an old stain or sealer on them, the Cedar Wash will penetrate it, dissolving the old stain enough to be washed off.

Why you should not use bleach when cleaning cedar:

The alternative to our formulas has always been chlorine bleach or TSP but the problem with those cleaners are that they leave the wood surface with a very unnatural bleached look, it also rarely comes out uniformly clean, more often than not it has a "blotchy" look that looks as if a bucket of bleach was thrown on the house. Once those products soak into the cedar and the sun beats down the almost "bake" in the sun, it causes extreme drying, making the shingles or shakes dry, thin and brittle. In addition, cleaning with bleach is also extremely detrimental to plant life and the eco-system around your home.

What pressure wash system you should use to clean your cedar:

The quickest way to wash is with a pressure washer but good results can come from light brushing with a scrub brush and a hose powered rinse this is all that is needed to clean up your cedar shakes or shingles and save them from rotting away. Using a garden hose and deck brush is one way of cleaning the cedar but it is slow, using a pressure washer is much faster. The key to pressure washing cedar is the pressure and the nozzle on the end of the pressure washer. Stock pressure washing nozzles put out a very sharp stream of pressure if you get the wand to close to the cedar you will leave a scar. Too much pressure is also bad, often dislodging or cracking the shingles or shakes. We recommend a nozzle called the soft tip that we had made for our cleaning technicians back when we had the cleaning company. We figured that if we could not teach the guys to avoid scarring the wood we could make a tip that would make it impossible to scar the wood. The Soft Tip has an "open mouth" the water comes out just like a hose nozzle, this open mouth reduce pressure by 75%. you could clean with 2,000psi and by adding the Soft Tip reduce pressure to about 500psi. We highly recommend adding a soft tip to your pressure washer when cleaning cedar. Unlike chlorine bleach and TSP the Cedar Wash will not harm the vegetation around the house, it also will not stain any painted surface or any fabric that it may come in contact with. Cedar Wash works great on all types of cedar or any type of natural wood. Use it to clean fences, decks, furniture, cedar siding or roofing, barn board and log homes.
