ABSTRACT:
A method and system are provided for enabling amateurs and non-professionals to restore faded or discolored color photographs and snapshots to their original condition by treating the faded or discolored color photographs and snapshots to clean areas with a remover of anhydrous acetone-free diacetone and coating or coloring the cleaned areas with a color corrective restorer comprising a powdered dye embedded or dispersed in anhydrous diacetone preferably in the relative proportions of 40 grains dye: 30 ml anhydrous diacetone or by using wax cube compositions of alcoholic paraffin or other suitable wax with acetone-free diacetone in the relative proportions of 100 grams wax in alcohol: 1-3 grams powdered dye therein in the optional presence of liquid glycerin and/or lecithin. Procedure and equipment as described for carrying out the invention which is characterized by the slower evaporation rate of diacetone as compared to denatured alcohol to provide adequate time to carry out the process steps.
