Abstract
This invention relates to a method for a single application of wood bleach that improves the degree of whiteness, uniformity and depth of bleaching in the wood. The method includes the application of sufficient quantities of wood bleach to maintain an excess of liquid on the surface of wood for an extended time such as a minimum of 10 minutes to obtain penetration to a greater depth. Periodic motion of an abrasive powder, or an abrasive pad to continually relocate the excess bleach on the wood surface, either by machine or by hand, provides even distribution and eliminates the raised grain on the bleached wood. Another aspect to the invention is a single step process of bleaching and dyeing in which the dye is mixed in the bleach solution.
