The invention relates to a hydrophobic and particulate soil removal composition and method for removal of hydrophobic and particulate soil from an article. Stubborn hydrophobic greasy or oily soils, including associated organic particulate soils, such as finely divided elemental carbon, are frequently encountered on hard surfaces including vehicle parts. The composition is selected to provide enhanced soil removal, preferably in vehicle cleaning applications. 1. A hydrophobic and particulate soil removal composition comprising:(a) a chelant;(b) an alkaline agent; [{'br': None, 'sub': 1', '2', '4', 'm, 'R—(OCH)—OH'}, {'sub': '1', 'wherein Rcontains about 6 to about 26 carbon atoms and m is an average value of 1 to 20;'}], '(c) an effective treating amount of an alkyl ethoxylate mixture containing two or more ethoxylate groups and having the formula [{'br': None, 'sub': 3', '2', '4, 'R—CO—R'}, {'sub': 3', '4, 'wherein Ris an alkyl group having about 6 to about 24 carbon atoms and Ris an alkyl group having about 1 to about 6 carbon atoms, wherein the composition is free of hydrocarbons; and'}], '(d) an effective treating amount of a coco-based fatty acid ester component having the formula(e) a surfactant.2. The composition of claim 1 , wherein the composition may be diluted to a usable product claim 1 , wherein the usable product comprises between full strength to about 1 part concentrated composition to 80 parts water.3. The composition of claim 1 , wherein the composition comprises between about 0.05 wt. % to about 20 wt. % chelant.4. The composition of claim 3 , wherein the chelant comprises of at least one of an iron oxide sequestrant and/or a metal oxide sequestrant claim 3 , such as aluminum claim 3 , calcium claim 3 , zinc claim 3 , and/or magnesium.5. The composition of claim 1 , wherein the composition comprises between about 0.05 wt. % to about 15 wt. % alkaline agent.6. The composition of claim 5 , wherein the alkaline agent comprises of sodium hydroxide ...
