1. A liquid fabric care composition comprising:
from about 10% to about 50%, by weight of the liquid fabric care composition, of citric acid and/or a salt thereof;
from about 0.01% to about 20% of fragrance material,
wherein the liquid fabric care composition is free of vinegar and acetic acid;
wherein the fragrance material comprises first aldehydic perfume raw materials,
wherein the first aldehydic perfume raw materials are characterized by at least one of the following structures:
R1—C(R2)(R3)—C(R4)(R5)—CHO,  a)
wherein R2, R3, R4, and R5 are independently selected from hydrogen or a hydrocarbon moiety,
wherein the hydrocarbon moiety may be substituted or unsubstituted,
with the proviso that at least one of R2, R3, R4, or R5 is a hydrocarbon moiety;
R1—C(R2)═C(R4)—CHO,  b)
wherein R2 and R4 are independently selected from hydrogen or a hydrocarbon moiety,
wherein the hydrocarbon moiety may be substituted or unsubstituted;
R1—Ar—CHO,  c)
wherein Ar is a substituted or unsubstituted aryl ring;
wherein for each of the structures according to a), b), and c), each R1 is independently selected from H, a substituted hydrocarbon moiety, or an unsubstituted hydrocarbon moiety;
from about 30% to about 90%, by weight of the liquid fabric care composition, of water;
wherein the composition comprises less than 5%, by weight of the liquid fabric care composition, of a material selected from the group consisting of detersive surfactant, bleaching systems, fabric softening materials, and mixtures thereof;
wherein the liquid fabric care composition is characterized by a neat pH of from about 2 to about 6.
