1. A method of rinsing a surface comprising:
applying a rinse aid composition to a ware in need of rinsing;
wherein the rinse aid composition comprises a surfactant system comprising:
(i) at least two surfactants according to the following formulas:

R1—O-(EO)x3(PO)y3—H  (A)

wherein R1 is a straight-chain C10-C16 alkyl, wherein x3 is from 5 to 8, and
wherein y3 is from 2 to 5,

R1—O-(EO)x4(PO)y4—H  (A2)

wherein R1 is a straight-chain C10-C16 alkyl, wherein x4 is from 4 to 6, and
wherein y4 is from 3 to 5,

R2—O-(EO)x1—H  (B)

wherein R2 is a C10-C14 alkyl with an average of at least 2 branches per residue, and
wherein x1 is from 5 to 10,

R7—O—(PO)y5(EO)x5(PO)y6—H  (D)

wherein R7 is a branched C8-C16 Guerbet alcohol, x5 is from 5 to 30, y5 is from 1 to 4,
and y6 is from 10 to 20,, wherein x is from 88 to 108, y is from 57 to 77, and z is from 88 to 108, and, wherein x is from 15 to 25, y is from 10 to 25, and z is from 15 to 25; and

(ii) optionally an additional surfactant according to the following formulas:

R2—O-(EO)x2—H  (C)

wherein R2 is a C10-C14 alkyl with an average of at least 2 branches per residue, and wherein x2 is from 2 to 4,

R6—O—(PO)y4(EO)x4—H  (E)

wherein R6 is a C8-C16 Guerbet alcohol, wherein x4 is from 2 to 10, and wherein y4 is, wherein x is from 12 to 20, y is from 120 to 220, and z is from 12 to 20.
