Abstract: Disclosed is a cleaning brush for cleaning toilet bowls and the like. The brush has a permanent handle and replaceable/disposable brush heads that are flushable after each cleaning. The brush is a stack of sheets of water-dissolvable and/or agitation-dissolvable material. The sheets can be attached together at an end by pressure bonding or by a water-soluble adhesive and formed with bristles at an opposite end. The wand provides a remote system for clamping and unclamping the brush head.

Abstract: An acid cleaner composition to remove deposits capable of reacting with the acid and also forming thereby hydrogen sulfide, comprising from about 5 to 95% by weight of an acid having an ionization constant of at least about 1.75.times.10.sup.-5, and an effective amount of a hydrogen sulfide scavenger agent providing a cation reactive with hydrogen sulfide to form a water-insoluble sulfide, whereby a substantial portion of the hydrogen sulfide is converted to said insoluble sulfide. The cations include Cu.sup.+2, Pb.sup.+2, Cd.sup.+2, Sb.sup.+3, and Sn.sup.+4, while typical acids are sulfuric, sulfamic, and oxalic. Preferred ranges, for a drain cleaner composition, are from about 40 to about 95% acid by weight, and from 2 to about 10% scavenger agent by weight. The compositions may be in solid form, or as an aqueous solution, containing preferably from 2 to 80% water. Corrosion inhibitors and carbon dioxide generating agents may be included.
