These methods include using household chlorine bleach, oxalicacid, or a concentrate hydrogen peroxide solution. PRODUCTS2.01 MATERIALS NOTE: Chemical products are sometimes sold under a common name. This usually means that the substance is not as pureas the same chemical sold under its chemical name. The gradeof purity of common name substances, however, is usually adequate for stain removal work, and these products should be purchased when available, as they tend to be less expensive. Common names are indicated below by an asterisk (*). A. Denatured Alcohol: 1. Other chemical orcommon names include Methylated spirit*. 2. Potential hazards: TOXIC AND FLAMMABLE.

THIS PROCEDURE CALLS FOR USE OF THE 30% CONCENTRATION. 3. Potential Hazards: TOXIC (when concentrated); FLAMMABLE (in high concentration). 4. Available fromchemical supply house, drugstore, pharmaceuticalsupply distributor, or hardware store. F. Clean, soft cloths G. Clean, potable water2.02 EQUIPMENT A. Glass or porcelain container B. Stiff bristle brushes C. Sponges D. VacuumPART 3---EXECUTION3.01 PREPARATION A. Wash wood using denatured alcohol to remove anydirt or other impurities from the surface. B. Sand the wood and remove any paint or varnish. Brush and/or vacuum dust and debris fromthe surface. C. Remove any grease or oil from the surface bywashing with mineral spirits and a clean, softcloth.3.02 ERECTION, INSTALLATION, APPLICATION CAUTION: DO NOT MIX AMMONIA WITH CHLORINE BLEACHES, A POISONOUS GAS WILL RESULT! DO NOT USE BLEACH ON BIRD DROPPINGS.

NOTE: TEST CLEAN A SMALL AREA BEFORE PROCEEDING WITH THEWORK TO DETERMINE THE BEST METHOD FOR REMOVING THE STAIN. NOTE: TOTAL REMOVAL OF A STAIN MAY NOT ALWAYS BE POSSIBLE. IN THESE CASES, LIGHTENING OF THE STAIN MUST SUFFICE. ONTHE CONTRARY, BE PREPARED FOR BLEACHED WOOD TO APPEAR LIKE-NEW IN CONTRAST TO SURROUNDING WOOD THAT APPEARS MORE AGED. NOTE: BLEACHES ARE WATER-BASED SOLUTIONS AND TEND TO RAISE THE WOOD GRAIN WHEN APPLIED; THIS WILL REQUIRE SANDING UPON COMPLETION. A. Stain Removal Using Household Chlorine Bleach: Recommended for removing an anilinedye finish and ink stains from wood. NOTE: BE SURE TO PROVIDEPLENTY OF VENTILATION; CAUTION: DO NOT MIX CHLORINEBLEACH AND AMMONIA. THIS WILL PRODUCE A TOXIC GAS. 1. Apply bleach to thestained area using a clean, softcloth or stiff bristle brush. Use straight fromthe bottle; 2. Allow to sit on thesurface for at least 10 minutes;reapply if necessary. 3. Thoroughly rinse thesurface with clean, clear water. 4. Allow to dry for atleast 24 hours before refinishing.

B. Stain Removal Using Oxalic Acid: Recommendedfor removing blue ink stains, ironstains and darkening or blackening of wood due to age orprevious cleaning. NOTE: BEST TO USE IT WARM ANDCONCENTRATED. 1. Dissolve crystals inhot water in a glass or porcelaincontainer. 2. Apply the solutionliberally to the surface using a clean,soft cloth or stiff bristle brush. 3. Allow to sit on thesurface for at least 10 minutes. It may take longer (up to an hour) to achieveeffective results depending on the type of stainand type of wood; agitate with a stiff bristlebrush if necessary to aid in stain removal; 4. Thoroughly rinse thesurface with clean, clear water. 5. Allow to dry for atleast 24 hours before refinishing. C. Stain Removal Using Concentrated Hydrogen Peroxide(30%): Recommended for lightening woods oras a last attempt at removing a stain before resortingto replacement. NOTE: HYDROGEN PEROXIDE ATTHIS CONCENTRATE IS THE STRONGEST OF THE THREE BLEACHESLISTED. IT IS TYPICALLY SOLD AS A TWO-PART KIT CONTAININGSODIUM HYDROXIDE.
