Acidic cleaning compositions for enhanced soil removal

An aqueous acidic cleaning composition comprising:

• about 40 wt-% to about 90 wt-% of aqueous nitric acid;
• about 20 wt-% to about 80 wt-% water;
• and
• about 0.01 wt-% to about 1 wt-% of at least two polyethoxylated fatty alcohols having different molecular masses wherein the polyethoxylated fatty alcohol is a blend of two C12-C15 ethoxylated alcohol mixtures with an average of 7-12 moles of ethoxylation, wherein the first polyethoxylated fatty alcohol is a mixture of C12-C14 ethoxylated alcohols with an average of 12 moles ethoxylation, and wherein the second polyethoxylated fatty alcohol is a mixture of C12-C15 ethoxylated alcohols with an average of 7 moles ethoxylation;
• and
• optionally about 0.01 wt-% to about 0.5 wt-% nonionic glucamide co-surfactant, and
• wherein the aqueous acidic cleaning composition is phosphate-free, sulfuric-free, and sulphate free;
• and
• wherein the aqueous acidic cleaning composition comprises from about 30% active nitric acid to about 45% active nitric acid.
