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.
