How about ComStar Pipe Dredging Agent Brand Introduction

ComStar is a world-renowned manufacturer of refrigerants, translated as "Kangxing" in China, which mainly produces hotel cleaning and food processing cleaning products in addition to refrigerants. 

In the field of pipe dredging agents, ComStar also has a good performance, its only Pure Lye 30-500 is currently the most outstanding product on the market, and its dredging performance is ranked first in the evaluation of professional evaluation websites Bestreviews and Bestadvisor.

Pure Lye 30-500 is a powdered bead form that avoids the problem of limited contact area between liquid/lumpy products and clogs, and is ideal for use in bathroom floor drains, with a 1 lb bottle for 2 uses for $12. Its formula contains 99% sodium hydroxide, which uses the special structure of powder particles to reach the blockage of the water pipe, and then uses the strong corrosiveness of sodium hydroxide to achieve a better dredging effect. BestAdvisor reviews show that Pure Lye 30-500 removes blockages such as hair and food debris and unclogs pipes in less than 1 minute.

It should be noted that due to the high purity of sodium hydroxide in Pure Lye 30-500, the danger is greatly increased, one or two powder particles can burn the skin, and the dissolution process will be accompanied by a pungent odor, so strict protective measures need to be taken when using, wearing gloves, goggles, masks, etc.

In addition, sodium hydroxide will produce a lot of heat when dissolved, which is easy to deform the pipeline, so it should be poured in a small amount many times and slowly when used, and it should also be avoided to mix with hot water above 30 °C, otherwise the hot wax generated by the reaction will damage and melt the pipeline, causing the pipeline to leak.

When using alkaline dredging agents, you may also encounter the problem that the sodium hydroxide in the dredging agent may saponify with the oil scale (higher fatty acid glycerides) in the pipes to form sodium stearate (the active ingredient of soap), and then completely block the pipes.
