Methods of inhibiting microbes from attaching to a surface and anti-adherent compositions are disclosed. One method can include providing an anti-adherent composition that includes an anti-adherent agent configured to inhibit microbes from attaching to the surface. The anti-adherent agent can be: Acrylates Copolymer, Trimethylpentanediol/Adipic Acid/Glycerin crosspolymer, Trimethylpentanediol/Adipic Acid Copolymer, Ethylhexyl Stearate, Ethylhexyl Salicylate, Acrylates/C12-22 Alkylmethacrylate Copolymer, Octocrylene, Ethylene Oxide/Propylene Oxide Block Copolymer, Polyquaternium-101, or any combinations thereof. The method can include applying the composition to the surface and allowing at least some of the composition to remain on the surface such that the anti-adherent agent inhibits microbes from attaching to the surface. The anti-adherent composition can include a humectant and can be non-antimicrobial.
