Abstract

Abstract An aqueous, non-alkaline, foamable bathroom cleaner that is particularly effective in removing lime soap residues and hard water salt deposits from sinks, bathtubs, shower enclosures and metal surfaces, and in maintaining toilet bowls clean when incrementally added to the flush water, comprising: 1. One to 30 percent by weight of an alkyl or alkylethoxy sulfate, 2. One to 15 percent by weight of a long chain alkyl diethanolamide, 3. One to 40 percent by weight of a short chain alkylbenzene sulfonate, 4. Two to 30 percent by weight of nitrilotriacetate or amineacetate, 5. 0 to 12 percent by weight of a conventional nonionic to anionic sulfonate surfactant, 6. 55 to 90 percent by weight of water, and 7. Mineral acid (sulfuric or hydrochloric) to adjust the pH within the range of pH 3-7.
