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... 

Similar to the technology used to produce cream cleansers, there are also formulas that can produce liquid toilet bowl cleaners with suspended abrasives [376,377]. The main difference between the cream cleansers and this type of product is that the suspending system should be acid stable instead of alkaline and/or bleach stable. Suspended particles are appearing in more and more of the toilet bowl cleaners. This has been commercialized in a gel form, which shows the suspended particles.
