NOTE: Chemical products are sometimes sold under a common

name. This usually means that the substance is not as pure as

the same chemical sold under its chemical name. The grade of

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. Solvent: Mineral spirits, turpentine or denatured alcohol.

       Mineral Spirits:

   1. A petroleum distillate that is used especially as a

       paint or varnish thinner.

   2. Other chemical or common names include Benzine* (not

       Benzene); Naphtha*; Petroleum spirits*; Solvent

PART 3---EXECUTION

3.01 ERECTION, INSTALLATION, APPLICATION

A. Dust with a solvent-treated soft cloth.

   along the grain of the wood.

C. Stain and Spot Removal: Stains may be cleaned by promptly

   wiping with cloth dampened in clear water or rubbing with

   cloth dampened in solvent. Dry the wood with a soft

   cloth. White spots may be removed by rubbing them with

   a small amount of linseed oil.

D. Old Stain Removal: If water and solvent fail to remove

   dark stains, brush full-strength bleach onto stained area

   and allow to stand one minute. Use clean, cotton rags to

   keep the bleach from running. TEST BLEACH IN A SMALL

   INCONSPICUOUS AREA PRIOR TO USING THE BLEACH ON THE LARGE

   STAIN TO ENSURE THAT IT WILL NOT DAMAGE THE WOOD.

   1. Rinse bleach completely from wood.

       small amount of stain to match original wood

       finish.

       rags, rubbing in direction of wood grain.
