A viscoelastic gel microemulsion acidic composition having a complex viscosity at 100 sec.sup.-1 of about 0.01 to about 0.07 Pascal seconds, a G' value of about 0.8 to about 0.3 dynes/sq cm over a strain range of 0.001 to 0.4% and a G' value of about 0.06 to about 0.6 dynes/sq cm over a strain range of 0.001 to 0.1% which comprises approximately by weight 0.5 to 7 wt % of a nonionic surfactant having an HLB of about 0.1 to about 8.0; 0.5 to 10.0 wt. percent of a sodium paraffin sulfonate 1 to 6 wt % of a polymeric thickener; 0.1 to 2.0 wt % of an aliphatic hydrocarbon or perfume having about 6 to about 22 carbon atoms; and the balance being water.

Thickened stable acidic microemulsion cleaning composition

An aqueous highly alkaline thixotropic automatic dishwasher composition containing alkalimetal tripolyphosphate, sodium silicate, chlorine bleach stable organic detergent active surfactant material, chlorine bleach compound, preferably sodium hypochlorite, thixotropic thickener, preferably montmorrilonite or attapulgite clay, and preferably chlorine bleach stable foam depressant such as a higher alkyl acid phosphate ester, caustic soda and soda ash.
