Weiwang can also be regarded as a first-line brand of household cleaning products in China, which belongs to Liby, mainly for high-end household cleaning, covering a series of cleaning products, with a good reputation in the Chinese market, and is the designated cleaning supplies supplier of Guangzhou Baiyun Airport.

Weiwang is close to Liby, the product positioning is in the middle and high-end, there are only two kinds of pipeline dredging agent, strong pipeline dredging agent and pipeline dredging liquid, the main ingredient is sodium hydroxide, the price is also relatively close to the people, the price of 3 boxes of solid particles is about 20 yuan, and the price of 500 grams of liquid dredging agent is about 15 yuan, which is basically the same as that of Mr. Weimei.

The strong pipe is the best-selling product, in the form of solid particles, in long packaging, directly poured and then filled with a small amount of warm water (lower than 30 °C) when used, and allowed to stand for 30 minutes to rinse with water, which is more convenient to use. The pipeline dredging liquid is in liquid form, the main component is concentrated sodium hydroxide solution, without dissolving steps, it can be poured directly and waiting, the effect is better than that of solids, but there is still a certain gap compared with foreign counterparts.

User feedback data shows that the effect of these two products of Weiwang is average, only for vegetable residue and hair, and may be ineffective in the case of serious pipeline blockage.

In the current Chinese market, there is no relevant industry standard for pipeline dredging, and there is a lack of effective evaluation system and regulatory measures, the technical content is not high, and small factories and even small workshops can also produce.
