An assessment of cleaning performance on surfacesother than ceramic tile cannot be presumed since there is noconfirmed basis for correlation for this soil on other surface orsubstrate types.5.2 The resu

Theresults of this guide should be compared to control treatments,which are incorporated into each performance evaluation.These result

Preparation of Soil6.1 Summary of MethodWhite ceramic tiles are soiledwith a composite soil composed

18、 of two separate preblends.One preblend consists of a mixture of synthetic sebum, metalstearates, carbon black, and dirt. The second preblend is apredissolved sodium stearate solution. Soil is applied using apainting pad applicator. The soiled tiles can be stored for up tothree months when stored at

19、 35F (1.67C). The soiledsubstrate is scrubbed with a fine-celled sponge, to which thedetergent system being tested has been applied, or with a dampsponge when the product is to be applied to the soil surface.Cleaning performance is evaluated by comparing reflectancemeasurements made on the clean/uns

20、oiled test panel, soiledpanel (untreated), and on the soiled panel after scrubbing witha straight-line washability apparatus. Results can be either avisual rating or calculated as a percentage of soil removed.6.2 Materials:6.2.1 Super Soilt Brand Potting Soil3, from local store,6.2.2 Palmitic Acid,
