• one or more of the following;
• a polyalkylene glycol, an ethoxylated alcohol, a polyalkylene glycol ether ethoxylate, an alkyl glucoside, an alkyl aryl sulfonate, an alkyl dimethyl amine oxide, and an alpha olefin sulfonate and a source of alkalinity, wherein said cleaning composition comprises less than about 0.5% by weight alkyl phenol ethoxylates.

A stable aqueous surfactant booster solution comprising a surfactant system comprising:

• the following combinations of surfactant:
• polyethylene glycol, a linear C9-C11 alcohol ethoxylate, (preferably with 5-6 moles of ethoxylation), an alkoxylated Guerbet alcohol (preferably with 3-10 moles of alkoxylation), a hexyl glucoside, a linear alkyl benzene sulfonate, a lauryl dimethyl amine oxide, and alpha olefin sulfonate.
