1. A method for pickling, the method comprising: pickling using a composition comprising HCl, urea, complex substituted keto-amine-hydrochloride, at least one alcohol selected from the group consisting of isopropyl alcohol and propargyl alcohol, an ethoxylate, and at least one ketone selected from the group consisting of methyl vinyl ketone, acetone, and acetophenone. 2. The method of claim 1, wherein the ethoxylate comprises an ethoxylated nonylphenol. 3. The method of claim 1, further comprising diluting the composition by 20-90% by volume composition in water. 4. The method of claim 2, wherein the composition comprises: HCl, 55 wt %; urea, 42 wt %; complex substituted keto-amine-hydrochloride, 0.067 wt %; isopropyl alcohol, 0.067 wt %; ethoxylated nonylphenol, 0.022 wt %; propargyl alcohol, 0.022 wt %; methyl vinyl ketone, 0.022 wt %; acetone, 0.022 wt %; and acetophenone, 0.0022 wt %. 5. A method for perforation cleaning, the method comprising: cleaning the perforation using a composition comprising HCl, urea, complex substituted keto-amine-hydrochloride, at least one alcohol selected from the group consisting of isopropyl alcohol and propargyl alcohol, an ethoxylate, and at least one ketone selected from the group consisting of methyl vinyl ketone, acetone, and acetophenone. 6. The method of claim 5, wherein the ethoxylate comprises an ethoxylated nonylphenol. 7. The method of claim 5, further comprising diluting the composition by 20-90% by volume composition in water. 8. The method of claim 6, wherein the composition comprises: HCl, 55 wt %; urea, 42 wt %; complex substituted keto-amine-hydrochloride, 0.067 wt %; isopropyl alcohol, 0.067 wt %; ethoxylated nonylphenol, 0.022 wt %; propargyl alcohol, 0.022 wt %; methyl vinyl ketone, 0.022 wt %; acetone, 0.022 wt %; and acetophenone, 0.0022 wt %. 9. A method for cleaning a filter cake, the method comprising: cleaning the filter cake using a composition comprising HCl, urea, complex substituted keto-amine-hydrochloride, at least one alcohol selected from the group consisting of isopropyl alcohol and propargyl alcohol, an ethoxylate, and a at least one ketone selected from the group consisting of methyl vinyl ketone, acetone, and acetophenone. 10. The method of claim 9, wherein the ethoxylate comprises an ethoxylated nonylphenol. 11. The method of claim 9, further comprising diluting the composition by 20-90% by volume composition in water. 12. The method of claim 10, wherein the composition comprises: HCl, 55 wt %; urea, 42 wt %; complex substituted keto-amine-hydrochloride, 0.067 wt %; isopropyl alcohol, 0.067 wt %; ethoxylated nonylphenol, 0.022 wt %; propargyl alcohol, 0.022 wt %; methyl vinyl ketone, 0.022 wt %; acetone, 0.022 wt %; and acetophenone, 0.0022 wt %.
