After the ceramic surface is contaminated, the difficulty of cleaning is called "anti-fouling performance". Products that are easy to clean have good "anti-fouling performance", and products that are not easy to clean have poor "anti-fouling performance". According to GB/T4100-2006 "Ceramic Tiles" national standard, there is no specific numerical requirement for the "anti-fouling performance" of ceramic tiles, but only the manufacturer is required to report the products produced to consumers to the level of "anti-fouling performance". That is, the indicator is a non-executive indicator.

In fact, the “anti-fouling performance” of ceramic tiles is very important for the use, and the polished tiles are the most prominent. Therefore, consumers can refer to the actual level of “anti-fouling performance” in the current industry and select products that meet the requirements of the paving place. Regarding the detection method of "anti-fouling performance", the national standard GB/T3810.14-2006 has clear guidelines for the anti-fouling performance test of ceramics. According to the "anti-fouling performance" of the products, it is divided into four types: A, B, C and D. level. Among them, Class A is the best and Class D is the worst.
