Abrasive Hard Surface Cleaner

Mild Abrasive Hard Surface Cleaner A mild abrasive cleaner for consumer use. Effective on Stainless Steel, Porcelain and other hard surfaces. 

Appearance White pasty liquid pH (as is) 7.0-8.0 Specific Gravity 1.47 

To a mixing vessel with sweep and scrape type agitation, charge the water and start agitation. Do not mix air into the product. Slowly add the Calcite followed by the Mazox LDA and the Potassium Citrate. 

In a separate vessel, dissolve the Calsoft F-90 in the remaining water. When completely dissolved, add the first part of the mix. Again avoid mixing excess air into the system. 

This formulation is designed to be used as is by the consumer It is a mild abrasive hard surface cleaner effective against most common soils. It can be used on stainless steel, porcelain and other hard surfaces. 

Add a mixture of the two surfactants to water. Allow the water to cool to 30C and continue to add the other components in the given order.

A wide variety of snrfactants including anionic and nonionic are widely used as shown in Table 10.45. Bnilder salts, snch as phosphates, EDTA-Na4, soda ash, and citrates, are also used. Certain special ingredients snch as ammonia or pine oil are product specific and are widely nsed. Alkaline sonrces are added to the formnlations, and they are available from caustic alkali, alkanolamines, silicates, and phosphates. Many hard surface cleaners contain some solvents typically they are alcohol, glycol ethers, or abrasive materials are preferable. Calcium carbonate, laponite clay, silica (Si02), alnmina (Al Oj), and titania (Ti02) are widely used as abrasive agents. 

Likewise, thickened aqueous hypochlorite compositions rely on these surfactants to accomplish the same purpose at alkaline pH levels of 11 or higher [47]. Desired viscosity for such formulas may range from 150 to 3000 cP. This would not only permit easy dispensing, but provides good coating action necessary for cleaning toilet bowls, bathroom tiles, and shower walls [48]. Effective viscosity control is also necessary to suspend abrasives found in scouring cleansers. Finally, the choice of the particular amphoteric surfactant is an important factor in the preparation of low solvent hard surface cleaners [49-50]. 

Hard-Surface Cleaning. Products used Tor hard-surface cleaning around the home include the hand- and automatic dishwashing products, the liquid and powder floor and wall cleaners, and the abrasive scouring cleansers. 

Abrasive cleaners arc used lo remove soils and stains from hard surfaces that are durable lo the scouring action. Such surfaces include stainless steel and porcelain plumbing fixtures, metal and ceramic cooking utensils, and various stone, metal, and ceramic building surfaces. Typically, these products consist of a very high level of abrasive (commonly silica flour) with moderate to low levels of a dry chlorine bleach (KDCC or chlorinaled trisodium phosphate) and low levels of surfactant (LAS) and builder (STP) for wetting action and improved stain removal... 

Even more sophisticated formulas with hypochlorite, surfactant, and abrasive materials have now been defined for specialized applications like toilet bowl cleaners. In this area, the patent literature discloses a hard-surface abrasive scouring cleanser comprising sodium hypochlorite up to 15%, abrasive like silica sand or calcite up to 70%, smfactants like anionic (soap, sulfate, sulfonate) or nonionic (amine oxide) or their mixtures up to... 

Another tank was installed in Stony Ridge, Ohio, USA and was removed in 1977 after 12 years and 9 months of continuous service. A photograph of the tank after removal is shown in Fig. 8.1. The exterior surface of the tank ends and the center joints had a white, somewhat chalky film, which easily scrubbed off with an abrasive cleaner. This surface effect was typical of air-cured fiberglass surfaces exposed to moisture over long periods of time. No areas of cracking or crazing were found on the inner surface. A section was cut from the tank wall on the side, and flexural properties and hardness...
