Abstract

Systems and methods are provided for removing a stain from a surface. A first solution is applied to the stain, wherein the first solution comprises a combination of an ammoniated substance such as ammonium hydroxide and an alcohol such as isopropanol. A second solution is then applied to the stain treated with the first solution, wherein the second solution comprises between approximately 6% and approximately 15% hydrogen peroxide.
