16 . A method of cleaning a vehicle surface comprising applying to the vehicle surface a composition comprising:
i. gluconic acid; and
ii. a complexing agent selected from the group consisting of polyamino acids, polycarboxylic acids, and mixtures thereof.
17 . The method of claim 16 , wherein the complexing agent is selected from the group consisting of polyaspartic acid, and a copolymer based on aspartic acid.
18 . The method of claim 16 , wherein the complexing agent is present from about 0.1 to about 75% by weight.
19 . The method of claim 16 , the composition further comprising a nonionic surfactant.
20 . The method of claim 19 , wherein the nonionic surfactant is selected from the group consisting of alkoxylated fatty alcohols, alkyl polyglycosides, and alkoxylated fatty amines.
21 . The method of claim 16 , wherein the composition has a pH from about 4 to about 10.
22 . The method of claim 17 , wherein the composition comprises from about 0.1 to about 30% by weight of polyaspartic acid.
23 . The method of claim 17 , wherein the composition comprises from about 0.1 to about 30% by weight of polyaspartic acid, and from about 0.1 to about 50% by weight of gluconic acid.
24 . The method of claim 16 , wherein the cleaning composition is diluted with water to form a ready-to-use cleaning solution comprising from about 0.025 to about 100 grams per liter of the complexing agent.
25 . The method of claim 24 , wherein the ready-to-use cleaning solution further comprises from about 0.05 to about 50 grams per liter of a nonionic surfactant.
26 . The method of claim 16 , further comprising rinsing the cleaning composition of the surface of the vehicle.
27 . The method of claim 16 , wherein the cleaning the composition is applied to wheel rims.
28 . A vehicle cleaning composition comprising:
i. gluconic acid; and
ii. a complexing agent selected from the group consisting of polyamino acids, polycarboxylic acids, and mixtures thereof.
29 . The composition of claim 28 , wherein the complexing agent is selected from the group consisting of polyaspartic acid, and a copolymer based on aspartic acid.
30 . The composition of claim 28 , wherein the complexing agent is present from about 0.01 to about 75% by weight.
31 . The composition of claim 28 , further comprising a nonionic surfactant.
32 . The composition of claim 31 , wherein the nonionic surfactant is selected from the group consisting of alkoxylated fatty alcohols, alkyl polyglycosides, and alkoxylated fatty amines.
33 . The composition of claim 28 , wherein the composition has a pH from about 4 to about 10.
34 . The composition of claim 29 , wherein the composition comprises from about 0.01 to about 30% by weight of polyaspartic acid.
35 . The composition of claim 29 , wherein the composition comprises from about 0.01 to about 30% by weight of polyaspartic acid, and from about 0.01 to about 50% by weight of gluconic acid.
36 . The composition of claim 28 , wherein the composition is diluted with water to form a ready-to-use cleaning solution comprising from about 0.025 to about 100 grams per liter of the complexing agent.
37 . The composition of claim 36 , wherein the ready-to-use cleaning solution further comprises from about 0.05 to about 50 grams per liter of nonionic surfactant.
