Abrasive Cleaners

Cleaning house means cleaning surfaces like floors, walls, windows, rugs and appliances. Except for rugs and upholstery, most household surfaces are “hard.” Technically, household cleaning is “hard surface cleaning.”

No single product can provide optimum performance on all surfaces and all soils. Thus, it is not surprising that many different household cleaners are available in the marketplace. They are formulated to clean efficiently and conveniently in the many different situations found in the home. Some are designed for more general use, such as all-purpose cleaners, while others are designed to work best on specific surfaces and/or soils.

Abrasive cleaners are designed to remove relatively heavy amounts of soil often found in small areas. They come in powder and liquid form and contain a kind of built-in elbow grease, which helps cut down on the hard rubbing required to remove soil. Scouring pads are also included in this category.

The abrasive action is provided by a variety of ingredients: small particles of minerals or a network of fine steel wool, copper, nylon or metal particles imbedded in a matrix of solid plastic.

The degree of abrasiveness of products varies. Over an extended period of time, the overuse of some abrasive cleaners can remove the glaze or coating from some surfaces. Always read and follow the surface manufacturer’s instructions before using a product.

Some cleaners disinfect surfaces. They include an antimicrobial agent to reduce the bacterial population that lives on soiled surfaces. Such agents can include pine oil, quaternary ammonium compounds or sodium hypochlorite. Such products will be labelled “disinfectant” or “kills germs.” In order to use this labelling, these products are regulated and approved by Health Canada.

Powdered cleaners have a long established place among household cleaners. Their cleaning and polishing action is provided by fine particles of minerals, such as calcite, feldspar, quartz and silica. In addition, powdered cleaners contain small amounts of surfactants for removing oily soils, such as the greasy film often found in sinks after dishwashing. Where removal of food, beverage, or mould and mildew stains is required, a bleaching agent is usually present. Where removal of rust stains is a performance feature of the product, oxalic acid or sodium hydrosulphite may be present.

Liquid cleaners are a suspension of solid abrasive particles in a thickened liquid matrix. They contain more surfactant and softer abrasives than are found in some powdered cleaners. As a result, their abrasive action is usually gentler than powders.

Scouring pads, like powdered cleaners, are products with a long history of use. In the most widely used types, a ball of fine steel wire provides the scouring action. For chemical cleaning and as a polishing aid, the steel wool pad may be filled with a cleaning mixture whose principal ingredient is soap.

Particularly on metal surfaces, the soap and metal pad can provide effective cleaning and a pleasing shine. On continued use, the cleaning mixture is used up and the pad begins to corrode.

Some scouring pads are made of non-corroding materials, such as a mesh of copper, stainless steel wire or nylon, while others are a plastic material imbedded with small particles of abrasives. These pads are not impregnated with a cleaning mixture and rely on mechanical action alone.

Other scouring pads consist of a cellulose sponge with a polyurethane backing. These pads significantly reduce the scratching of surfaces.
