According to the invention, the compositions and methods provide for the complete removal of labels, synthetic glues and/or adhesives from a plurality of surfaces through the use of an aqueous or non-aqueous basic organic solvent and/or an amidine, optionally in combination with surfactants, chelants, acidulants and/or additional bottle wash additives. Beneficially, the compositions and methods are suitable for use at lower temperatures and pH conditions, along with under caustic-free and/or reduced caustic conditions to effectively remove such labels, synthetic glues and/or adhesives from a surface within less than about 30 minutes.
