Liangjing and Willus, Weixin, and Mom are the brothers of a mother's siblings, and jointly belong to Willis Group, which is a large-scale daily chemical enterprise in Guangdong, has set up a number of bases at home and abroad, and is a long-term partner of McDonald's.
 
Willis Group has factories in China and South Korea to jointly produce and sell its products. Among them, in South Korea, there is a Korean version of Limn with baking soda as the main formula, due to imports and different formulas, the price of Korean version of Lumin is higher, 500 ml costs about 30 yuan, and 500 ml of domestic Bright Net is about 10 yuan. There is not much difference in the cleansing power between the two, but the Korean version of the brightening ingredient is relatively mild, which is suitable for users with sensitive skin.
 
In the evaluation of China's "Consumer Reports", the bright and clean toilet cleaner ranked third overall, with excellent wall-mounted performance, but the total acidity and surfactant content of the product are lower than those of Mr. Vermeer and Weiwang, and the cleaning effect is not so good, but due to the low price, it is still a recommended product for families who clean the toilet frequently.
 
The product line of Bright Clean Toilet Cleaner is very thin, in fact, there are three models of Bright Clean, Strong, Bright, and Powerful Fragrance to choose from, but the outer packaging is basically the same, only a very small line in the middle is marked, and the actual formula is almost the same, so it makes little difference which one to buy. All three products use organic acids and surfactants as the main ingredients, and they are relatively good at removing dirt.
 
Liangjing has also launched a toilet cleaner, but compared with similar products in terms of performance, durability and price, there is no particularly bright spot, it is a relatively mediocre product, and consumers can buy it on demand.
