Patent ID: 8017569

Claim:
An aqueous acidic aqueous hob cleaning composition having a pH of from 0.001-3.5 free of water insoluble, particulate abrasive materials comprising: 0.01-5% wt. of a surfactant blend comprising ethoxylated quaternary amine based surfactants with nonionic alcohol ethoxylate surfactants having 9 to 11 carbon atoms and 3 to 6 mols ethoxylation, wherein the weight ratio of the ethoxylated quaternary amine based surfactants to the nonionic alcohol ethoxylate surfactants is at least 1:1; 0.01-5% wt. of an organic solvent constituent comprising one or more glycol ethers selected from the group consisting of: propylene glycol methyl ether, dipropylene glycol n-propyl ether, and, propylene glycol n-butyl ether; optionally up to 7% wt. of at least one cosurfactant selected from anionic, cationic, amphoteric and zwitterionic surfactants.
