Abstract: A two-part liquid product, the first of which comprises a first solvent and a first dissolved dye; and the second of which comprises a second solvent and a second dissolved dye. The two solvents are immiscible. The first dye is insoluble in the second solvent, and the second dye is insoluble in the first solvent. Each dye is a different color than the other. Initially, when placed in a single container, the two parts form two separate different colored layers that do not mix. Shaking the container produces a temporary micro-emulsion. The emulsion has a new color representing the combination of the colors of the two component layers. This combination color indicates to the user that an emulsion exists and that the product is effective. The component materials are selected so as to produce a stable emulsion for between five to twenty minutes before separation.

Abstract: The invention relates to compositions and methods for cleaning both smokeless powder and black powder firearms comprising about 10 to 99 wt % of a fatty acid alkyl ester blend and about 1 to 25 wt % of at least one alkyl glycol ether, and additives designed to enhance the solvency and cleaning properties of the composition.

Abstract: The invention relates to a high flash point aromatic, aliphatic hydrocarbon petroleum solvents optionally combined with specific ingredients to provide maximum solvency, penetration, saturation, dissipation and dispersion of the solid deposits. It has very low evaporation, high flash point (>100° F.), low freezing pour point, corrosion protection and increased cleaning efficiency.
