WOOD KOTE

Mix equal parts of component “A” (hydrogen peroxide) and component “B” (sodium hydroxide solution) in a clean plastic bucket. Do not use a metal container. Mix only the amount required for bleaching. Apply solution with a bristle brush or synthetic sponge. Apply evenly to clean dry wood surface. Wet area thoroughly and completely, but don’t flood. Rinse brush/sponge in clear water several times during application to avoid contamination of the solution. Bleach is self-neutralized when completely dry, usually after 24 hours.

KWICK KLEEN

Apply liberal coat of part “1” (sodium hydroxide solution) to entire surface. Allow to penetrate approximately five to 10 minutes. While surface is still wet, apply liberal coat of part “2” (hydrogen peroxide), and allow to dry overnight. Repeat bleaching if more color needs to be removed. When final color is achieved, neutralize surface with mixture of two parts water with one part vinegar. If repeated bleaching is necessary, sand wood between applications.

HAZARDS

Wood bleach has some specific hazards associated with it. The first set of hazards is to the people applying it. Follow the manufacture’s instructions to minimize risk when working with hazardous materials. Eye protection is needed to prevent splashes from contacting eyes, and since the sodium hydroxide solution can cause chemical burns on the skin, a full face shield may be necessary. Always use properly rated gloves and protective clothing to make sure any splashes do not contact skin. Work in a well ventilated area.

The next set of hazards is to prevent mixing wood bleach with any other materials. Many materials commonly found in a wood finish shop can produce a hazardous reaction with wood bleach. The components of wood bleach are incompatible with acids, bases, combustibles, metals, salts of metals, reducing agents, flammables and most other organic materials. So, don’t mix anything with wood bleach except according to the manufacturer’s instructions. If the wood bleach is contaminated, pressure can build up in a sealed container causing it to rupture.

STORAGE

Storing wood bleach may seem an after thought, but because of the hazards associated with it mixing with other common items, care should be taken in determining a storage location. The wood bleach should be stored in its original sealed container and at least 25 ft. away from the above mentioned incompatible items. This is especially useful to lessen the risk of contact in the event of a fire. Sodium hydroxide will produce hydrogen gas when exposed to some metals. Hydrogen gas is highly flammable. Hydrogen peroxide, when exposed to a fire, can decompose and produce large amounts of oxygen. Also, oxygen can be produced when exposed to some metals. One part produces hydrogen gas and the other produces oxygen; both of these can greatly intensify a fire.

Your insurance company can help with advice on storage to minimize risk of fire and unwanted reactions. Check with federal, state and local government agencies to make sure you are taking all necessary precautions. Wood bleach can help provide that lighter and brighter final color you may need on some projects. Just be sure to follow the proper precautions.
