Guidelines

Here are some things you must know when bleaching.

  1. The surface to be bleached should be free of all wax and other foreign substances, including the finish coat, so that the bleach can penetrate evenly.
  2. Once the bleaching is finished, the bleached area must be neutralized and all residue removed. Otherwise the bleach will act on your new finish. Mix a cup of borax in a quart of hot water, allow the mixture to cool, and apply it to the bleached area with a cotton swab. Blot the area with absorbent paper; then apply clear water with the swab to rinse. Blot again, and allow the area to dry for at least 24 hours.
  3. If any of the bleach ever comes in contact with your skin, rinse it with clear water. Don't wait. Do it instantly. The longer the bleach stays on the skin, the greater the danger of burning.
  4. If any bleach splashes into your eyes—

1 The black marks on this surface were caused by water They are in the wood, not just in the finish To get rid of them, you need these materials for bleaching: a two-part wood bleach you can buy at your home center; some vinegar, a lot of cotton swabs; and three little cups. The cups we use came from a photo developing kit and are numbered This makes it easy to remember where each chemical is.

2 Begin by applying Chemical A from the kit. as directed Remember that these are powerful and dangerous chemicals. Wear rubber gloves and eye protection (in case of accidental splashing) and follow the manufacturer's directions exactly as written.

3 After the specified time, use a cotton swab to apply Chemical B from the kit There will be a white foaming action

5 Here is the spot after drying You can see that the black marks have disappeared There was stain on this surface and it, too. is gone Your first refinishing step will be to stain this spot first to bring its color level up. Allow it to dry, then apply a coat of stain to the whole top.

4 As a final treatment, apply vinegar and water to the spot to neutralize the other chemicals Use a mixture of two parts water and one part vinegar After a few minutes, blot up the vinegar and allow the spot to dry.

even the tiniest drop— wash them out immediately with clear water in an eye cup. Then go directly to your doctor or hospital emergency room. Do not take any chances. The danger may be slight, but vow can't judge it. Let a professional take care of it.

  1. Do not sand any wood that has been bleached until the bleach has been neutralized and rinsed away. This is because the sanding dust will contain fine particles of the bleach that you will inhale— and you certainly don't want a powerful bleach at work in your nasal passages and lungs.
  2. If any bleach gets inside of your rubber gloves or splashes on your clothing, take the glove or clothing off quickly and rinse the skin area with clear water. The fabric may make the danger of burn greater by holding the bleach against the skin like a poultice.
