Claims9
An aqueous cleaning composition to be applied from a squirt bottle comprising
- (a) about 5 up to 20 weight percent of particulate abrasive selected from the group consisting of diatomaceous earth, calcium carbonate, Ca.sub.3 (PO.sub.4).sub.2, Ca(PO.sub.3).sub.2, zeolite feldspar, zirconium silicate, calcium silicate, titanium oxide, ZnO.sub.2, CaO, Al.sub.2 C.sub.3 and silica;
- (b) a two part thickener consisting essentially of a mixture of fumed silicon dioxide and smectite clay, the fumed silicon dioxide being present in weight percent amount between about 1 and 5, the clay being present in weight percent amount between about 4 and 15;
- (c) about 18 up to 40 weight percent weak aqueous hypo-halite bleach solution, the hypo-halite selected from the group consisting of sodium hypochlorite, potassium hypochlorite, calcium hypochlorite, magnesium hypochlorite, lithium hypochlorite and hypobromite;
- (d) about 2 up to 15 weight percent alkaline builder salt selected from the group consisting of potassium carbonate, Na.sub.2 CO.sub.3, NaOH, KOH, Na.sub.4 P.sub.2 O.sub.7, K.sub.4 P.sub.2 O.sub.7, Na.sub.5 P.sub.3 O.sub.10, K.sub.4 P.sub.3 O.sub.10, Na.sub.3 PO.sub.4, K.sub.3 PO.sub.4, NaSiO.sub.3, Na.sub.2 O:
- 2SiO.sub.2, and
- (e) water in an amount which is in excess of 50% by weight of the composition.
