A method for staining/finishing wood carried out within an automated or a semi-automated flatline wood staining/finishing system, for the enhanced visualization of a natural grain pattern in wood products, with a stain formulation containing more than one between fluorescent dyes and pigments in a fluid vehicle, the method comprises: A. Preparing a natural unfinished wood stock for staining, said natural unfinished wood stock having a grain pattern characterized by a natural distribution of sapwood and heartwood, by sanding said unfinished natural wood stock, as needed, to remove surface imperfections; B. Reducing the intensity of said grain pattern of said unfinished wood stock, lightening natural color of said sapwood and heartwood of said unfinished wood stock or evening out color differences between heartwood and sapwood of said natural unfinished wood stock by bleaching said natural unfinished wood stock with an aqueous bleach solution selected from the group consisting of (i) a two part liquid formulation containing hydrogen peroxide and sodium hydroxide, (ii) a chlorine bleach and (iii) oxalic acid; C. Neutralizing said aqueous bleach solution in said natural unfinished wood stock by first contacting said natural unfinished wood stock with water, and then with an aqueous solution containing baking soda mix; D. Repeating Step B and/or C as desired at least one additional time; and E. Staining said natural unfinished wood stock with a stain formulation containing more than one between fluorescent dyes and pigments in a fluid vehicle, at least one of said dyes or pigments being fluorescent when exposed to activating electromagnetic radiation in the UV and near UV band of the electromagnetic spectrum, and each of said dyes or pigment having different color than the other, so as to enhance visualization of said grain pattern in said natural wood products in the absence of activating electromagnetic radiation, wherein at least one of the foregoing steps is pre-programmed and performed within said flatline system, by automated equipment within said flatline system.
